I was told when I asked about rooms that would hold 4 that on the upper decks, none of the rooms rear of the aft elevators would hold 4 people because of the design of the ship. The man said that so much structural stuff was running between floors that there was no room for the extra bed to be stored in the ceiling. Whether it is true or not, I have no idea. I asked the question here and thought surely someone would post that they had stayed in one of the aft rooms with the 4th bed, but no one did....so maybe it is true. If you call and ask DCL, they will tell you.
According to the diagram in the DCL brochure, no those rooms dont hold 4. From what I can see, the furthest ones aft, on that deck, that hold 4, are 6122 and 6622.
