Hi Camilla, 

thank for your message As a first, simple approach, if you are sure about not letting reservations with more than a year come in, you can use a close to stay restriction with a maximum advance of 365 days (or another relative period), for All rates and All spaces.

You can use Active from start of starting today and leave Active until end of empty.

That would essentially close all possibilities of booking for more that X days in advance (365 in my example).

I really hope this works for you. Please, don’t hesitate to leave your comments here so we can discuss further.

Best,

Ivan
