@Amanda1958 You'll just have to wait to hear from the guest. If you need to get in to clean and prepare for the next guest, pack up the guest's belongings and put them elsewhere and message them to let them know you need to do this.
Did you send a check-out reminder the afternoon before? That's an important thing to do. "Hi XX, hope you are having a good stay. Just a reminder that your check- out time tomorrow is 11am and I can't be flexible on that as the cleaning needs to commence at 11:15 to prepare for my next guest. Please also make sure to leave enough time to do the things mentioned in the check-out instructions. Thanks for booking with me."
