Just back from Liberty of the Seas, Western itinerary. Cruising were my husband 37, myself 33, my son 19 months old, my parents 67 and 68.
We flew down to Miami the night before and stayed in Miami Beach. Took taxis to the cruise terminal and arrived a little around 11:15 AM. We were on the ship by 11:45 AM. It was a very quick and easy embarkation. No problems. We did board after the eastern itinerary, no Belize stop before us.
We had a balcony stateroom 6632. Nice room close to the aft elevators, which we needed with our son. We were also right above the promenade and our dining room. It was a good location.
