We love Deck 2. Been there twice, going again in June! You are within stair distance of the restraunts and theaters (except, of course, Palo), and are close to the disembarkation exits. This is key, because the elevators can be a bit of a pain (kids like to play on them, they get full, and they can take a bit of time to get to your floor).
Deck 2 is the best value, IMHO!
