Huh, this topic really caught my eye. We recently came off a 10 day caribbean cruise on the Equinox. We were in a deck 6 balcony which is above the entertainment deck. Right below us were specialty restaurants and a bar. We had a constant banging noise in our cabin for the whole 10 days. We had supervisors listen and verified that there was indeed a problem. One day they had the ceiling removed to inspect but to no avail. It was then determined that the noise was coming from deck 5 below, but the source was never located and the noise never ceased. I have to admit that they did try to fix things for us and finally did offer us some fcc. Even with some loss of sleep during our 10 day adventure, we did enjoy our cruise and will be sailing with Celebrity again.
