My sister and I sailed on the Liberty of the Seas in early December to Belize and Cozumel on a 5 night trip. It was FANTASTIC in our views! There were only a couple of minor issues, but nothing that I wouldn't expect on any other vacation.
Embarkation: Worse part was getting from the airport to the terminal at around noon on a Saturday. There were 7 ships leaving port that day, so it was a bit busy. OK, the lines were a little long at the terminal. We brought our own suitcases (I mean, really, how much do you need on that short of a trip), and the lines snaked back and forth but moved along at a steady pace. LOTS of agents checking you in. We proceeded on board and our cabin was ready, so we dropped off the suitcases, left a note for extra towels and to make the bed into two beds and went exploring. Had lunch at the Windammer, a drink at the Hoof and Claw, went through the safety briefing on deck, and watched the ship depart from the helipad (great place to watch). I think we were the fifth ship out, so it was fun to watch the others maneuver into place and exit the port.
Cabin: We had been upgraded to a balcony from an outside stateroom about a week before; from now on I’ll always want a balcony! Room was very large and comfortable, with lots of storage once you started looking around. Stored the suitcases under the bed, and with the built-in cabinets on either side of the big mirror and in the bathroom, we had plenty of space for small stuff, plus the shelves and hangers in the closet. Had some rambunctious young folks next door making lots of noise the first night, but after speaking to them from the balcony, they were much quieter. Our room steward was very attentive to any of our requests and always seemed available.
