We stayed in 8540. It's in the same location as 8040, but on the starboard side. It is midship, near the elevators (but not too close) and convenient to the pools and spa. The only problem with this area is that you can sometimes hear the pool chairs being moved on Deck 9 early in the morning. It did not bother us, but la ight sleeper may be awakened by it. Have a great time.
