We returned in August from the wonder and we were in room 6144 far aft, portside. We had no problems at all with the room, very quiet, right near the aft elevators. We have booked cat 6 for next August but have gone this time for midship, starboard, just to see what it is like to have a varandah with plexiglass and not the metal varandah we had in 6144. We could not see out to sea at all when sitting on the varandah in this room.
Although, in choppy seas not being able to see out may not be a bad thing (lol.)
