Sailed to Belize and Cozumel with Royal Caribbean on 1/2/2016. The ship was clean and cabins were comfortable. Most of the following information is probably available if you know where to look but just want to share:
1) 18% gratuity for all drinks is added your bill even if you have the drink package.
2) Getting off the ship at Belize is very unorganized. You need to take a transport from the ship to the dock. It was so disorganized one of the passengers decided to take over by providing directions and guidance. It felt like it was the first time the ship had stopped at Belize.
The cabin was clean. We had 3 adults in the cabin and was told there would be pull out. No pull out instead it was a pullman from the ceiling over the bed. Not very comfortable and if you have mobility problems you would not be able climb the ladder to the pullman.
