Class cancellation window: how many hours?

A class's cancellation window depends on its size. In a class of twenty, two to four hours is enough. In a class of six, you need twelve to twenty-four. The window exists to give someone else time to take the spot, and it only works when it applies the same way to everyone.

The number comes from the size of the class

The smaller the class, the earlier you need to know. In a class of twenty, a spot that opens two hours before gets filled. In a class of six, the queue is not long enough for that to happen on its own.

Class sizeWindowWhy
15 to 25 spots2 to 4 hoursThere is almost always a queue, and it gets decided on the day.
8 to 14 spots6 to 12 hoursThe spot has to open up the evening before.
Up to 8 (reformers, small group)12 to 24 hoursThe queue is short and the week gets planned in advance.
Starting values. The right number is the one that fills the spot at your gym.

A window that is too long also costs. With 48 hours, booking becomes a two-day commitment, and some people stop booking. A spot nobody booked is worth the same as a spot someone dropped.

Cancelling late and not showing up are different things

Someone who cancels outside the window at least gave notice: the spot goes back on the calendar and can still be filled. Someone who does not show up and says nothing keeps the spot blocked until the end.

It is worth counting them separately. The two hurt in different ways, and each needs a different answer: the first is fixed with an earlier window, the second with a consequence.

The consequence, and where it wears out

There are three options, from mildest to hardest: the class counts as used, the spot is blocked for a few days, or there is a charge. The first is the mildest, and it is the place to start.

What breaks a rule is the exception, more than how hard it is. Applied to some people and not others, it ends up decided case by case at the front desk. If the system applies the rule, the same for everyone, nobody has to defend it at the desk.

And there should be a way to dispute it. A no-show marked by mistake (the person was there, the coach did not mark them) is fixed with a request and a reason, without an argument at the door.

The cancellation window is set once, in the booking rules, and applies across the space. Class booking software

Frequently asked

What about someone with a real emergency?
The human decision is still there: someone with permission removes the no-show, and who did it and why is recorded. The difference is that it becomes a noted exception, and the rule itself does not bend.
Should I use the same window for every class?
Not necessarily. A class of six and a class of twenty at the same gym can have different windows, because the problem the window solves is different in each.
Does being on the waitlist use up a class?
It should not. Until the spot is taken, there was no class. Charging people for waiting teaches them to stay out of the queue, which is the opposite of what you want.
How many hours should a class cancellation window be?
It depends on the spots. In a class of fifteen to twenty-five, two to four hours. In one of eight to fourteen, six to twelve hours. In one of eight or fewer, twelve to twenty-four. The right window is the one that gives someone else time to take the spot.
