We just completed the the Carib loop on the Navigator of the Seas and our general opinion was that the ship is definitely up to the usual RC standards.
The food on the cruise was quite good and of very fresh character. The staff was polite and helpful and ship in general was exceptionally clean.
Our cabin was well outfitted and everything therein worked well.
Small cabin, windowless, but as experienced cruisers we left the balcony staterooms to the new cruisers in our group! Comfortable beds and airconditioning system that works well.
