Have you handled the situation when a guest about to arrive contacts you, he tells you that he has to move the dates of his trip by "X" circumstance, you make the modification to the reservation to later dates, and once the reservation cancels you. Leaving your Cancellation Policy without effect because by moving the dates they already have the necessary days to make the 100% refund valid?
What would they do in that case? Greetings
