We have a triple room booked for the 2/27/05 Mariner and according to their site, the room has two twins (able to move together to make queen), and the sofa bed. As far as I know, this room does not have the beds in the ceiling/wall. I'm not sure I could sleep with someone so close over my head. I hope when we get onboard, the bed situation is what we expect!
