A tour minimum numbers policy comes down to four decisions, made in this order. Set the minimum at your break-even number of riders. Set a decision date from the earliest hard deadline you face, and show it to guests before they pay. On that date, count the riders who have booked: at or above the minimum, you run. Below it, work down a short ladder: move the guests to another departure, run anyway if the loss is one you have decided to accept, or cancel and refund. Then tell every guest the same day, with a clear next step. The rest of this guide shows how to do each of the four, with worked numbers you can replace with your own.
A tour that misses its minimum is not a failure. What costs you reviews and refunds is a late, vague or inconsistent decision. If you set the rule in advance, you stop deciding under pressure on the morning of the ride, and you stop treating each guest differently.
This guide is written for anyone who runs scheduled bike tours, in the UK or elsewhere. RideLoop makes booking software for bike rental, tour and holiday operators, so we have an interest in the software side: use the checklist near the end on every system you shortlist, including ours. Some legal examples come from the UK and are named as such. The method applies anywhere, but rules on cancellation and refunds differ by country and state, so operators outside the UK should take local advice.
01Step 1: set the minimum where the departure stops losing money
Your minimum should start from arithmetic, not instinct. A departure has a fixed cost that does not change with group size, such as the guide and the van, and each rider adds a price and a small cost of their own, such as lunch. The number of riders at which the departure breaks even is the fixed cost divided by what each rider adds, rounded up.
Here C is the fixed cost of the departure, p is the price per rider and v is the cost of each extra rider. The numbers below are invented, and you should swap in your own. A seat costs £75, the guide is £150 for the day, the van and fuel come to £90, and each rider costs you £10. The fixed cost is £240 and each rider adds £65, so the break-even is 240 ÷ 65 = 3.7 riders, which rounds up to 4. Those figures run through the rest of this guide.
Three judgement calls sit on top of the arithmetic.
- Margin. Break-even is the floor. If your costs are uncertain, such as a van you pay for by the mile, set the minimum one rider higher.
- One minimum per product. A half-day ride, a full-day tour and a multi-day holiday have different fixed costs, so they need different minimums. The same tour may deserve a different one in the shoulder season, if your guide or van cost changes.
- Ride quality. Some operators set the minimum a rider or two above break-even because a ride with two guests can feel flat. That is a business judgement, and it should be a number you chose, not one that drifted in.
What counts toward the minimum
A minimum is a number of riders, not bookings: a party of four counts as four, and it cannot be split in half. Beyond that, decide in advance which bookings count, and write it into your policy, because this is where disagreements start.

| Booking state | Counts? | Why |
|---|---|---|
| Paid in full | Yes | The rider has committed |
| Deposit paid | Yes | The rider has committed, and the balance is due before the departure |
| Unpaid hold | No | It can lapse, so it should not be relied on to run a tour |
| A party booking | Yes, by head | A family of four is four riders, and they travel together |
| Staff, guests of the guide or comped places | No | They do not pay, so they do not cover the fixed cost |
| A private booking on the same date | No | It is a different departure with its own minimum |
02Step 2: set the decision date by working back from departure
The decision date is the last day you will decide whether a departure runs. Choose it by listing every deadline that bears on the decision, taking the earliest, and leaving a day to act. Four kinds of deadline usually matter.
- Supplier cut-offs. The last day you can cancel the van, release the guide or cancel a lunch or accommodation booking without paying for it.
- Your guests' travel. A guest who has booked a ferry, a train or a night away needs enough notice to change plans. A decision 48 hours before the ride is no use to someone arriving from abroad.
- Your guide's calendar. The day on which a guide who is not needed can take other work.
- The law, where it sets a latest date. For some tours it does, as the chart shows for the UK.
Suppose a one-day tour has a van you can cancel free up to five days before, a guide you must release a week ahead to keep them for other work, and mostly local guests. The earliest deadline is the guide’s, at seven days, so the decision date is seven days before the ride. A week-long holiday has a different set of deadlines, and as the next chart shows, a legal one too.
The contract may set an earlier period. Packages under 24 hours without overnight accommodation are outside the regulations.

| Trip length | Latest notice before the start |
|---|---|
| Trips of more than 6 days | 20 days |
| Trips of 2 to 6 days | 7 days |
| Trips under 2 days | 48 hours |
Two habits make the date work in practice. Put it on the booking page before the guest pays, in plain words: "This tour runs if at least four riders have booked by 7 days before. We will tell you by that date either way." And add an earlier checkpoint, such as seven days before the decision date, when your software or your calendar shows you which departures are short, so you can push them with a message to past guests or a post, before you have to decide.
03Step 3: apply the decision rule on the decision date
On the decision date, count riders using your counting rule. If the number is at or above the minimum, confirm the departure and tell guests it is running. If it is below, go down this ladder in order and stop at the first option that works.
- Rung 1: Merge.Offer to move the booked riders to another departure of the same tour that has spare seats. Of all the options this one usually does best, because you keep the revenue and add no fixed cost.
- Rung 2: Reschedule.If a date that works for the booked riders exists soon, move the whole departure. This needs each guest to agree.
- Rung 3: Offer a supplement.You can ask the booked riders whether they would pay a little more per head to run as a small group. They can say no, and they keep their right to a refund.
- Rung 4: Run anyway.Do this only if the loss is within a loss budget you set before the season.
- Rung 5: Cancel and refund in full.
The loss budget is the most you are willing to lose on a single departure to keep faith with guests. It is a number you choose in advance, such as £50. It does two jobs: it takes the emotion out of the decision, and it makes sure two guests in the same position get the same answer.
Here is the rule running on the invented numbers from step 1, with a loss budget of £50. With three riders booked, the departure loses £45, which is inside the budget, so you would run it if merging and rescheduling were not possible. With two riders it loses £110, which is outside the budget, so you merge, reschedule or cancel. The chart shows what each option is worth with three riders booked.
Assumes costs are still avoidable on the decision date.
View as table
| Option | Result per departure |
|---|---|
| Merge into another departure | +£195 |
| Cancel and refund in full | −£4 card fees |
| Run anyway | −£45 |
| Loss budget (illustrative) | −£50 |
The chart assumes your costs are still avoidable on the decision date, and that is why step 2 matters. If you miss the supplier cut-offs, the guide and the van are paid for whether the tour runs or not. Then the fixed cost is gone either way, and running with three riders earns £195 against a cancellation that still costs you the £240. The decision date should be the day your costs stop being avoidable, not a day after.
If you are weighing up a tour with a rising booking count, you can allow a short extension: for example, 48 hours if the count is one rider short and bookings have been arriving in the last few days. Write that down as part of the policy too, with the new date shown to guests. Extending the date without a rule is how a policy turns into a habit of deciding late.
04How to cancel a tour with low bookings
When the ladder ends at cancelling, do these eight things on the same day. Doing them in order keeps guests informed and your costs down.
- Step 1: Check your own terms.Look at what your booking terms say about minimum numbers, notice and refunds, and follow them. If the tour is a package under UK rules, the notice dates in the chart above apply as well.
- Step 2: Recount.Make sure no late booking or pending payment changes the number. A recount takes a minute and saves an awkward reversal.
- Step 3: Record the decision.Note the date, the number of riders, the rule you applied and who decided. If a guest asks why, the answer is already written.
- Step 4: Tell the guests.Contact every booked rider the same day, using the templates in the next section.
- Step 5: Refund in full.Return everything the guest has paid to the card or account they paid with, including any deposit, and do not deduct the card fee from them. Check the processor’s timing: Stripe’s documentation says a card refund appears with the customer approximately 5 to 10 business days later, depending on the bank, so tell guests to expect that.
- Step 6: Cancel your suppliers.Release the guide, the van, the lunch stop or the accommodation while it is still free to do so.
- Step 7: Close the departure.Take the date off your booking page so no one books a tour that is not running, and tell anyone on a waiting list.
- Step 8: Follow up.Offer each guest the next departure, and make a note of the cause. If the same tour misses its minimum three times, the problem is usually the date, the price or the marketing, not bad luck.
05Step 4: tell guests, and tell them well
The cost of cancelling is smaller than most operators fear, but it is not zero. In the earlier example, three £75 bookings paid by standard UK cards cost £1.33 each in card fees, about £4 in total. Stripe’s published pricing says the processing fees from the original transaction are not returned, so that is a cost you carry. The bigger cost is the goodwill you spend, which is why a quick, clear and generous message matters more than the refund mechanics.
How you say it matters as much as what you decide. Five habits cover most of it.
- Send it the same day you decide. Do not wait to see whether a late booking turns up.
- Lead with the decision. The subject line and the first sentence should say whether the tour is running.
- Say what happens to their money. A full refund, to the card they paid with, and roughly when to expect it.
- Offer a next step. A named date or a clear alternative, not "let us know".
- Make the refund as easy to choose as anything else. If you offer a new date or a credit, offer it alongside the refund, never instead of it.
Here are four templates. Replace the details in square brackets, and keep each message short.
Hi [name], your place on [tour] on [date] is confirmed so far. The tour runs if at least [minimum] riders have booked by [decision date], and we have [number] at the moment. We will tell you by [decision date] either way. If you have a friend who would enjoy it, this is the link: [link].
Hi [name], I am sorry to tell you that we have to cancel [tour] on [date], because not enough riders have booked to run it safely and well. We have refunded the full [amount] to your [card/account], and it should appear within about 5 to 10 working days, depending on your bank. If you would like to ride with us on [next date], I can move your booking at no cost. Just reply to this message. Thank you for understanding.
Hi [name], [tour] on [date] has not reached its minimum of [minimum] riders. We can move you to [new date], which has space. If that works, reply "yes" and we will do the rest. If it does not, we will refund you in full instead. Either way, please tell us by [reply date].
Hi [name], we have reached the number of riders we need, so [tour] is going ahead. Your meeting point is [place] at [time]. We will send a final message with the weather and what to bring on [date].
In each message, give your name and a way to reach you, and avoid phrases such as "unfortunately due to unforeseen circumstances". Say what happened: not enough riders booked.
06What the law says (UK example)
07What minimum numbers tour booking software should do
A policy is easy to write and hard to follow on a busy week. Minimum numbers tour booking software earns its place by carrying out the policy for you, so no departure passes its decision date unnoticed. These are the things to look for.
- A minimum on every departure.Set per tour, and changeable on a single date, with the counting rule from step 1 applied: paid and deposit-paid riders count, unpaid holds do not.
- Headcount against the minimum, always visible.On the admin screen, a departure should show riders booked, the minimum and how many are still needed.
- A decision date on every departure.It should also appear on the guest booking page, before payment.
- An at-risk list.One screen that shows every departure below its minimum, sorted by decision date, so the soonest decision is at the top.
- Actions that match the ladder.From that list you should be able to confirm, move riders to another departure, reschedule, or cancel, without rebuilding bookings by hand.
- Notices and refunds that follow the decision.Messages to guests and refunds should be prepared for you to approve, using templates you can edit. Be wary of anything that cancels and refunds with no approval step.
- A record.A log of who decided what and when, and a report of how often each tour misses its minimum.
To test this in a demo, set up a departure with a minimum of four and book three riders. Check the system flags it as at risk and shows the decision date. Then move one rider to another departure and cancel the first: the refund and the message to the remaining guests should be queued for your approval. If you are doing the work in a spreadsheet or by hand at that point, that is the gap.
Run the same test on RideLoop. Our features page lists, under guided tours, headcount against the minimum, which runs are at risk and the decision deadline, and our homepage describes confirming, merging or cancelling before the deadline. We would like you to hold it to the same test as every other system.
08What to avoid
These are the mistakes that turn a quiet departure into a complaint.
- Avoid: No written minimum. If the number lives in your head, it changes with your mood, and guests will notice.
- Avoid: A decision date later than your costs allow. Once the guide and van are paid for, cancelling costs you more than running.
- Avoid: A decision date earlier than you need. Deciding ten days out for a tour with free cancellation until three days out throws away bookings that might still arrive.
- Avoid: Silence. Not telling guests is the worst way to cancel. A message on the morning of the ride is a message too late.
- Avoid: Credit instead of a refund. Offer credit or a new date as extra choices, and keep a refund as easy to choose.
- Avoid: Keeping the deposit. If you cancel because of low numbers, the guest has not had the service, so the deposit goes back.
- Avoid: Blaming the guest. "Not enough bookings" is a plain statement. "You booked too late" is not.
- Avoid: Different answers for different guests. The same numbers should get the same decision, every time. That is what the loss budget is for.
- Avoid: A minimum hidden in the small print. Put the minimum and the decision date on the booking page, before the guest pays.
09Common questions
Can I cancel a tour if not enough people book?
Often yes, but only on terms you have set out clearly in advance. For a package under UK rules, the minimum must be stated in the contract and you must give notice within the legal limits shown in step 2. For other tours, your booking terms should state the minimum and the decision date, and you should refund in full when you cancel.
How do I cancel a tour with low bookings?
Recount, record the decision, tell every guest the same day, refund in full to the original payment method, release your guide and van while that is still free, and close the departure on your booking page. The eight steps above set out the order, and the templates in step 4 give you the wording.
How much notice do I have to give?
For a UK package, the notice must be within the period fixed in the contract and no later than 20 days before the start for trips of more than six days, 7 days for trips of two to six days, and 48 hours for trips under two days. For other tours, your own terms apply, but a decision date that gives guests a week or more is kinder and usually matches supplier deadlines better.
Do I have to refund guests if I cancel?
In practice, yes, in full. Where it is a package, the regulations give a full refund when the organiser cancels for low numbers. Otherwise, the Consumer Rights Act grey list described above treats keeping money for a service you did not supply as potentially unfair. You can offer a new date or a credit as well, but the refund should be just as easy to choose.
What is a sensible minimum number for a small-group tour?
Start with your break-even: the fixed cost of the departure divided by what each rider adds, rounded up. Then add a rider if your costs are uncertain. In the invented example above, that was four riders.
Should I run a tour with one or two riders?
Only if the loss is within your loss budget, or if they are happy to pay a supplement. Otherwise, offer a merge, a new date or a refund. A private tour at a private-tour price can be a better answer than a tour you run at a loss.
What should a tour minimum numbers policy say?
It should state the minimum, which bookings count toward it, the decision date, what you will do if you miss it, and how guests will be told. Put it on the booking page before payment.
Does the minimum apply to private groups?
No. A private booking is its own departure with its own price and its own minimum, so it should not count toward a scheduled departure.
Is a weather cancellation the same thing?
No. A weather cancellation is a different decision with a different policy, and it should be written separately. This guide covers low numbers only.
10Where to go next
If you are comparing systems for scheduled departures, start with the UK buyer's guide to bike rental software and the 12 questions to ask before you choose. To see how RideLoop shows headcount against the minimum, which runs are at risk and the decision deadline, look at the features page.
Facts and figures were checked on 2 November 2026. The riders, prices and costs in the worked examples are invented to show the method, so replace them with your own. The legal sections describe the position in the UK in general terms and are not legal advice. If a trip could be a package, or your terms are unusual, ask a qualified adviser before you rely on them.
