You can pre-approve, which makes it possible for the guest to book if they don't meet the Instant Book criteria. I think it's made clear to host and guest alike that pre-approving doesn't block your calendar. They don't get 24 hours to make up their mind. They get a day in which the pre-approval works. After that, they have to ask again. In the meantime, the place is open to others!
I'd be happy you're popular, pre-approve people in you want (or send a text reply which is neither accepting or declining) and let people know they need to be quick or the dates may go!
