Chose the Oasis of the Seas because we had never been aboard her. We have cruised on the Freedom of the Seas many times and she used to be our favorite.
The crew on the Oasis seems to be a very happy crew. All crew members we passed in the corridors always had a smile and a "hello". This attitude is apparently passed down from the Captain because we encountered him on numerous occasions and it's obvious that he enjoys his job.
There is so much to do and see aboard the ship that it's impossible to be bored. All the venues and shows, especially the water shows, were great.
Cabin layout was excellent. Plenty of storage and adequate room to move around. Balcony was not huge, but more than adequate for 2 people.
