Having been on RCL before, we were eagerly looking forward to this trip. We went the extra mile and got a suite!
We got aboard easily, although the folks at the terminal were not particularly nice. The Navigator is a beautiful ship, with public areas spacious and immaculate. With over 3000 people aboard, we never felt crowded, except during the muster drill.
I am out of nice things to say. We are experienced cruisers, having been on at least a dozen. We have been on Carnival, RCL, and Celebrity.
With a suite, you are entitled to "concierge" service. This entitles you to priority reservations at the spa, restaurants, shore excursions, etc.(or so we thought). This service got us absolutely nothing. The concierge said " sorry, sold out." on all of these items. So, if you are sailing on the Nav- don't go to your cabin, go and make whatever reservations you want immediately!!!
The a/c in our suite did not work when we arrived. Someone from maintenance worked on it for over an hour to fix it. When we returned to the cabin later, the a/c was still not functioning. After another hour, they got it to work.
The food in the dining room ranged from fair to inedible, though the waiter and assistant tried their best. The food in the Windjammer was also in the same range. As you read above, we did not try the fancy "add-on" restaurants. Johnny Rockets was exactly what you would expect it to be.
Cozumel was the only stop on this trip. An excellent place to spend a day. Naturally, the ship folk try and send you to shop at stores they sponsor.
They do have a very nice game room on the Nav, which occupied some of the many teens aboard.
All in all, very disappointed with RCL, and will look elsewhere for our next cruise.
