A cancellation policy is the contract between a club and its players about what happens when a booking can't be honoured. A clear, fair, consistently-enforced policy is one of the highest-ROI changes a club can make: it reduces no-shows, it increases the chance of re-selling the slot, and it sets the tone for how the club is run.
The tradeoff
A strict policy maximises captured revenue but feels punitive and pushes some players to look elsewhere. A lax policy feels friendly but trains players to over-book "just in case", which inflates no-shows. Most successful clubs land in the middle: free cancellation up to a defined window (often 12–24 hours), no refund inside the window unless the slot is re-sold.
Implementation matters
Whatever the policy is, it has to be (a) written down, (b) shown at the moment of booking, and (c) enforced uniformly. Selective enforcement is worse than no policy — it teaches players the rules don't apply to them if they complain loud enough.
