I was on the JOY in January and had a creaky room when the sea rocked. As it turned out It was coming from the TV housing attached to the wall and desk. It sounded like a tennis ball bouncing inside the wall. Couldn't sleep from it. It took several persistent calls to an assistant manager and eventually they "found" a room when they initially said they didn't have any of my type of room. The new room exactly the same size only one deck up and on the other side of the ship. They also gave a complimentary specialty dining to any restaurant for the inconvenience. They also had a bellhop type guy move the bulk of our stuff. They do mark in their system notes about rooms that have had complaints the assistant manager told me; as he said someone had complained about sounds from the kids gaming room nearby, but I never heard anything in the new room. It took a couple days to get this settled. We were grateful. a 15 day cruise, it would have been maddening to deal with that thumping for over 2 weeks.
