Iam writing this because one of my listings an hotel with four rooms show listed on this website, had a reservation of one of the rooms this october leaving three of them free.
So how can i limit of reservations to three rooms for that period?
If your intention was to allow separate bookings for each room, there need to be 4 separate listings - one listing for each room. If you have 1 listing for (up to?) 4 rooms, you can only host 1 group (=1 booking) at a time regardless of how many rooms the guest booked and have access to.
