I agree with Marc and Jim's observations.
For me the most serious issue is the design that caused there to be no aft elevator or stair access to deck four where Compass Rose and the theater are located. If you have mobility issues, DO NOT book a cabin in the aft half of the ship. Otherwise, you will have to walk a long way to the forward elevators to get to deck four, and then walk back to get to Compass Rose.
While the rest of the criticisms are valid, they would not stop me from cruising again on the ship.
Tom.
