We just got off the Allure of the Seas 7 day Med. tour starting in Barcelona. My husband and I have cruised a fair amount... 6 on Carnival, 1 on Princess, 1 on Celebrity, 3 on Silver Seas and 2 on Cunard ( Sea Goddess when they were still part of that line). Carnival Liberty was the largest ship prior to this one, and also a European cruise. There were 8 in our group, our 3 adult children and their significant others.
Here are some notes from the cruise.
1: As others have said, embarkation was very smooth. From cab to cabin in perhaps 20 minutes? Some of the rooms were ready at 12:30, others not til 1:00pm. We checked in at noon, and went to the Windjammer for lunch.
Cabin: We had 12624... ocean balcony. The room was quite comfortable for 2. Bed very comfortable, sofa, coffee table. Bathroom has a good amount of storage. Lots of closet and adequate drawers. NOTE: only shampoo and bar soap provided. No conditioner or shower gel as some ships have. The balcony was quiet, but often too hot. Also in port, our views were mostly of industrial ports. We could use it in the evening but really too hot on this summer cruise during the day.
Our kids ( 22-34 years old) had adjoining cabins on deck 11 overlooking Central park. I loved these cabins. It is definitely quieter there, and they still get the sky and a fair amount of breezes. And the sun did not heat up their room/ balcony like ours. Their steward opened the dividers between their balconies for them.
I liked our location as we were midway between the 2 elevator/ stair banks.
We chose to let this be a relaxing day, so just took the Royal Caribbean shuttle, either 5 dollars or 5 euro round trip, and walk about the lovely town for a while, back on the ship early to relax. If you go behind the cathedral and to the right, it is the older town with small windy streets and more local shops.
