If the room is supposed to sleep 4 then you would definetly have the ceiling pull down bed. Without it the room would only accomodate 3. The way the rooms are set up is the two twins that can convert into one king, the sofa bed which is the sofa flipping over to reveal a bed on the other side and the ceiling pull down, upper bunk bed over the sofa (the only exception beside the suites is that the cat 4 has an additional bed that pulls down from the wall, like a murphy bed).
