I have been on 3 previous cruises, 2 on Royal Caribbean (Mariner of the Seas to the Caribbean & Monarch of the Seas to Ensenada) and 1 on Princess (Regal Princess to the South Pacific). I am in my mid 30's.
The Ship is beautiful as expected of a brand new ship. Public Rooms were kept immaculate. The main area wasn't as impressive as the grand Promenade on the Mariner of the Seas.
The Dining Room Food was excellent. The Dining Room Service was a below expected, but this maybe because we had anytime dining, and didn't have the same waiters everyday. The Buffet Food was terrible, the flow was terrible, and it was always very hot in the Buffet. You could never get a table at the Buffet area. The poolside pizza & burger grills were excellent!
