Personally, I feel it is waaay too crowded for four adults to cohabitate comfortably, and we are not big people. In January, DS, 18 years old, and I spent five nights there in a room with 2 double beds. It worked out great. Our next trip, January 2008, DH and DS, 20 years old, will be coming along, so I have booked two connecting rooms, one with a king bed and the other with two doubles. If you have seen pictures of the rooms, in a room with two doubles, the door opens up almost right into one of the beds. It's pretty crowded for two, but butt-bumping time for a party of four.
