We had 4 people (2 adults and 2 kids). Now the two kids are 14, but are 5'10", 180 lbs, so they are adults. We were cozy. Sofa bed is a joke. If you are taller than 5'6", you will have your head or feet hanging off.
The room view was great, back end of the hump, nice location. Great location to steps, elevators and promenade.
