Well, just about everything I had heard about the Oasis was true. The ship is spectacular. Central Park was amazing, The Boardwalk was just like being "by the sea" and the Aqua Theater was impressive. We loved the kid-free Solarium area. The Flo-Rider and Zip line were tons of fun.
I didn't get the impression that the ship was full, as there were tons of empty pool chairs available during peak sunning hours.
There was never a problem getting into any of the shows that "required" reservations even though we had none.
14175 great location, inside cabin, close to stairs and elevators but not noisy.
