Welcome to CC @Caralee2
Have you used related keywords in the search box here in CC to see if anyone else has been in a similar situation & how they resolved it?
Maybe block off the days you are going away so you don't get bookings for those days.
You could also edit your listing to say that you may take a longer response rate at the moment - they won't know how long it's been like that
I've been guilty of bumping my rate way out of my normal rates when I've had other things on so my listing is still visible - it just aims it to another sector of the market who may know someone who is looking in future..
All the best
