I am having a difficult time setting up booking parameters for "Available days of the week" during different times of the year. We have a lake house, and in the summer prime months we like to book 7-day rentals, Saturday to Saturday. The rest of the year, we would like to open up or booking availability to anytime, with a minimum of three days, and check in and check out can be anytime of the week. I called Customer Service, and they said it can't be done. I don't believe that is the case. Is there a way that I can set up different booking parameters such as minimum night stay and different check in & out days during different times of the year. Or is there a third-party app that can control this for me?
