We had stateroom 2114 on our Dec 2004 cruise. It is on deck 2 and very close to the elevators.
When at CC you could see the guests get off the ship, the christmas tree and snow machines were great to look at, especially when you get up in the morning.
We didn't have any problems with noise, and with the room being on deck 2, it was a great way to burn off te extra calories.....we used the stairs very often
