IMO...if I could not get a deluxe on the club level...than I would get the cot and stay in the regualr club room...I loved it that much. The regular room seemed a bit more roomy than most hotel rooms, and there were 2 sinks, one in the bathroom and one right outside, so that would be a big help with 5 people.
I would do it with a cot...just stay close to the lounge...and you can eat breakfast and snacks in there instead of in the room. The older kids will be able to go by themselves.
