We stayed in 6622. It was a nice room and verandah....however we did have lots of kids running the halls and seemed like there must be some room across from our cabin where the stateroom hosts get supplies because we heard quite a bit of noise from them banging around stuff. This would not make not choose this cabin again though.
The hallway on this side of the ship was much narrower than the opposite side...my SIL and BIL were over in 6154... and I noticed this when we were walking to get them and them up to the elevators. We all liked deck 6.
