Plans change, and the earlier you cancel, the better. You can cancel for a full refund until 24 hours before your service date begins — midnight in the operator's country, the night before. After that, a change or refund is up to the operator.
If you don't cancel and don't turn up, the operator keeps the payment for the service. A security deposit on a hire car or charter is still returned to you, because it was never part of the price.
Running late rather than not coming? Message the operator from your booking page. Most will hold a room or a pickup if they know.
