This is our 5th cruise, 3 on Disney, 2nd on Oasis of the Seas. We sailed the eastern Caribbean in January 2010, and now did the western Caribbean Sept 18-25. On our first Oasis cruise, we booked two more cruises because we loved the ship, the food, and the kids club and nursery onboard. Up until the Oasis, only Disney had a nursery and a place parents could drop off their kids under 2 years old for a few hours.
I'm writing this on the say I got back from the cruise so everything is still fresh in my memory.
Me (37), wife (37), daughter (3.5), and son (15 months) all shared a category D3 room, deck 10 starboard, room 610, pretty much in the middle of the ship. Last cruise we were on deck 14 midship. Being high up on deck 14 was cool, but since deck 14 is below the pool deck (15), a few nights were noisy with late night pool parties. Deck 10 was very quiet every night and we loved that. Deck 14 was nice because that is the deck where the kid's club/nursery were, but being on deck 10 wasn't a huge problem.
