You should enjoy this stateroom-- we were in 8056 (with other family members in 8054, 8058, and 8060) on the Magic a few weeks ago and loved the location of these rooms, which are between the aft and midship stairs/elevators. It's a very quick walk up to Topsiders, the 24-hour drink station, and all the other stuff on Deck 9 (pools, fast food, ping pong, etc.).
We thought it might be noisy with so much activity going on above us, but we heard NO noise in the room itself. From the verandah we could hear people running/walking on the deck above, chairs being moved, etc., but it was never annoying.
Our only "complaint" was that the starboard side of the ship had better views (of the harbor) while we were in port at St. Maarten and St. Thomas. But I guess you can't have everything!
