All regular rooms at the Polynesian and CR sleep 5. Most rooms at the GF do too although the daybed there is not a full size twin. It is a bit more narrow.
Lots of rooms at Y&BC sleep 5 but the daybeds there are not twin size either..seem shorter and more narrow to me. I think the same is true at BWI. The rooms at these resorts are smaller too.
The regular rooms at AKL and WL do not sleep 5. At AKL, deluxe rooms offer a little more space and can sleep 5 for a steeper price. WL has junior suites or whatever the current name is that sleep six again for a higher price.
The cabins at Fort Wilderness sleep 6. Bedding includes bunk beds, a double bed and a fold down bed in the LR. Can't remember if it is a queen or double.
Depending on your 5, I would pick the Polynesian, CR or FW cabin if you want one room.
