My wife and I, our five children and one friend sailed on 2/15 for a 5 night cruise to Belize and Cozumel. This was our 3rd cruise, having sailed on Disney and Carnival. I was a little apprehensive about Liberty and RC after reading some of the reviews, but I've come to realize that many people set unreasonably high expectations or give a negative review based on one or two trivial bad experiences. I also notice that many people expect a cruise to be the same experience as dining at a 5-star restaurant, which it's not. If you insist on 5-star dining, you're better off going to NYC or San Francisco and staying in a hotel.
The good points: The boat is fantastic, new-looking, and very upscale. We never lacked for things to do. If you have kids, you'll never see them because they'll be on the mini golf course, rock wall, basketball court, rock wall, or flow rider which is absolutely amazing. The walking/running track on deck 12 was great to use in the morning, as was the fitness center.
Everything was really clean. Even the public restrooms were luxurious. I saw workers cleaning railings, glass, door handles, elevators etc. on many occasions. They constantly required you to clean your hands with sanitizer at the dining area entrances and whenever getting off and back on the boat (not sure why other reviewers would complain about this?).
