we stayed across the hall in 6556 last Oct/Nov - the location is PERFECT!!! In fact, we're going again this Nov and wanted to be closer to the mid-ship elevators because it is so easy to get around. WE decided to go down to the 2nd deck (and spend the difference at the spa lol) and we're farther back so I'm hoping it works out as well.
If you do a search on 6556, there were quite a few people who have been in that room so you can get an idea of the location
