This is a review of the Navigator of the Seas, sailing date Nov 17, 2012. Our group was my wife, myself, our children (ages 20, 12, and 12) and my wife's (mid 70s) parents.
As a general statement I believe the crew on any given ship will make or break the entertainment value of the vacation.
The crew on the Navigator just didn't seem to care and weren't trying to hide it. We are a pretty laid back, self-entertaining group and don't expect to be waited on hand and foot, so we can and did have a good time despite the crew. That said I could not in good conscience recommend this ship/itinerary to someone.
We had both adjoining cabins 9230 and 9232. We never heard any hallway or neighbor noise. Reasonably close to the forward elevators. Overall a good location.
