I don't think they all sleep five. We were told when we made the reservation that it had to be noted that there were five of us so we would be sure to get a day bed.
Also, I agree with wolfelaw. The room we had in concierge was a closet! It only had double beds, not queens, and we couldn't get out to the balcony without moving furniture. Maybe if our three kids had been smaller, but it was way too small for teens and adults. No, I take that back...it would have been too small for five under any circumstances.
