We sailed from Galveston on Dec 8th. The Navigator pales in comparison to our past cruises from Galveston on Mariner, Voyager and Rhapsody. On all our previous Royal Caribbean cruises, everything from the crew to the food to the entertainment was wonderful..
The ship itself is lovely and it was decorated for Christmas which was nice. There is a lot of art around the ship that is interesting and fun to look at. The public areas were clean and inviting. We enjoyed the steamroom and sauna and fitness center. We had a great time in Grand Cayman and Cozumel on DIY excursions. We walked around the port in Falmouth which is really just an extension of the ship with the same prices on everything. What we've seen of Jamaica during this and previous cruises is gorgeous so next time we will book an excursion to see more of it.
On this cruise, we found the crew to be somewhat unfriendly and in some cases, rude. For instance man-handling (expensive) personal items when returning to the ship from port and saying things like "my time is valuable" when people on vacation weren't moving fast enough for them.
