We sailed on the 5/10-5/17 Eastern Caribbean voyage with a group of 14 family members (four parents and 10 young adults). This this was my first cruise on RC and only my second overall. We had a great time and would like to share some feedback on the various aspects of Liberty of the Seas:
The Ship itself: Fantastic and very clean. Other than a constant foul odor on some parts of the Sports Deck, everything looked and seemed spotless. Obviously the ship is huge but it really wasn't a burden at all to get from one side to another. Overall I would say it was easy to navigate and not get lost. There is a very useful ship map on the wall next to every elevator.
Cabin: We stayed in Interior Stateroom #9691. While it was only 152 sq feet, there was enough room for us to unpack and put away all of our toiletries and clothes. The bed was surprisingly spacious and comfortable. We didn't spend much time in the room so having no window wasn't a big deal to us.
