I don't think the connecting rooms have anything to do with bed size--they are for families with more than 4 people who need to stay at a value resort. We have a family in my subdivision with 5 boys, ages 4,5,6,8 and 10. They almost booked the All stars last year but CRO could not guarantee connecting rooms. I'm hoping they will get a better answer with Pop Century, it sounds more large-family friendly. (And no, they can't afford the DVC villas).
