@Colleen253 Yeah, right. Block my calendar for the busiest, most expensive time of year, and then cancel with a full refund on Dec. 23rd. How about,
"Hosts have only a few cancellation policies to choose from, we don't have the option to customize our own cancellation policy. My policy is strict for the exact reason that I can't have a booking blocking my calendar, only to be cancelled, leaving no time to be able to rebook the dates. So no, I cannot be flexible on this."
How much you want to bet these are the kind of guests who'd choose the pay half up front option, and then think they were due back 50% of the 50% they paid if they cancelled.
