Hello @Ray-And-Vicki0 & welcome to ABB CC from across the miles in Auckland, New Zealand
There's several different cancellation policies and also an Alteration to reservation Policy option which is perhaps lesser known which is very helpful to know.
The later allows one to alter/ modify an existing reservation by either Host or Guest with mutual agreement.
It gives one perhaps a better playing field balance to offer or decline to offer a Guest a refund of any kind for whatever reason dependent on the circumstances - say you have a Guest that's booked for several weeks or a month who despite chats is not agreeing to Terms of Service.
Hosts can send a request to alter/modify their reservation and shorten their stay and offer a partial or no refund for the rest of their stay, or maybe something has come up that a great guest has to leave early for unexpected reasons and you want to offer a refund.
Here's the link - use the "change" option if you want to open up your calendar.
