Hi Mark, I have never been on Navigator of the Sea but I have taken 9 cruises on the same class as the Navigator, the Mariner of the Sea. I have taken 42 cruises in the past 6 years and this class of RCCL ships is by far my favorite. On Sept 6 I am taking another cruise to the Mexican Riviera on the Mariner, that's how much I like this class ship. I also look forward to visiting Madera, the Canary Islands and Nassua. I always enjoy staying in Fort Lauderdale on returning to the States.
I frequently book an inside cabin and this class ship has PR
(Prominade Roooms) which overlook the Mall in the center of the ship.
The only thing I dislike about Royal Caribbean lines is that they do not offer the best single suppliment prices. I do think that RCCL have the most beautiful ships.
