This was our first trip on Oasis and we would book again without hesitation. We loved all of the entertainment, dining and activity on board. We thought the layout of the ship was very organized and never got lost. The service was wonderful and every employee seemed genuinely happy to be on board and very helpful. We booked everything in advance so we did not have to wait in line for anything. We never took the elevators so we cannot comment on wait times. The Diamond lounge was wonderful and Rami the concierge always greeted everyone with a smile. The only dining venu that we would not return to is Chops - we felt that the service and food were not very good- when we mentioned this to the manager when we were leaving he did not seem to care and took our cabin number but never sent us an apology or anything. We loved the wine choices and appetizers in Vintages. The shows were all wonderful - we did not see Cats because we had seen it on land. 150 Central Park, Sabor and Izumi were all spectacular! We had late seating and the food and the service in the main dining room was very good. It was nice to have so many choices and activities on board and we never felt like the ship was too crowded. We are looking forward to sailing Oasis again.
