Then you might see where the problem is - perhaps one of the nights is sold out and the hotel has decided to overbook anyway if you stay 3 nights but not 2.
Yep, this.
The other thing that might happen if you search each of your two nights is there might be individual nights available Friday and Saturday in different room types. If this is the case you can do two different bookings (provided you can work with the room types, of course). The property might actually make you move rooms, but often times finds a way to make it work. I've definitely had this happen before.
