I stayed in A-632 last Feb. on the Sea Princess. It was an outside balcony and we didn't notice too much noise from above. One night we heard something rolling around on the deck a little, but it t was after the beauty salon had closed. Hope this is a help.
thanks both of you for your responses. I usually try to get a room between two cabin decks due to a bad first cruise experience. We were under the show room, which we thought would be okay for sleeping late in the mornings, but lo and behold - the dancers practice in the morning!! LOL Live and learn.
