We just came off the 4th sailing of the new MARINER OF THE SEAS, the Eastern Caribbean itinerary, and both my husband and I agree that this was the best cruise we have ever been on, and this makes cruise #22 for us.
Of course being the largest ship afloat, along with Royal Caribbean's other 4 Voyager-class ships, is part of the reason and also the fact that it is the newest ship sailing.
All the staff and crew seemed to go out of their way to be friendly and especially helpful. It was obvious that they were not new employees; in fact most we talked with have had numerous years sailing either on Royal Caribbean or other cruise lines.
