I was on the Conquest (same size as Valor) and had a cabin right around the corner from the elevators. They do have live music in the Lobby each night and the sound does carry all the way up the atrium, but it usually goes until midnight. It's a great location for a cabin because it is close to the elevator, but you might also hear the elevator if you are within one or two cabins away from the elevators...I never had a problem.
