I was in a King Suite in February. It has a king sized bed in the bedroom with an upholstered chair, dresser, tv and closet. The living room area has a sofa bed, desk, desk chair and another upholstered chair and, of course, another tv. There is one bathroom. It would sleep four comfortably. I'm not sure if you can fit a rollaway in there -- don't know where you would put it. It's like having adjoining rooms only one is a living room and one is a bedroom (with one bathroom on the living room side).
If you have any others questions, I will try to help.
