Hi @Emily2378
There are different ways to do this. I would say the easiest and most straightforward is to:
1) Change your minimum stay (the first field under the "Availability" tab in your calendar) to minimum 30 nights
2) Then, also under the availability tab, create a "custom trip length" for each of the unbooked gaps from now to February 2025. You can set a different minimum stay for each of these open stretches, depending on your preference.
Another way to go about it would be to use professional tools, but the above will work just as well. Once you receive 30-night bookings, there will most likely be gaps between the long bookings again, which you can fill in the same way (by setting custom trip lengths between bookings).
