This was my second time on adventure so now I've done both southern itineraries. The ports are great and offer a nice variety. I enjoy the promenade this class offers. We found the crew friendly and happy which creates a nice culture. Most of the shows were excellent. There was just one I didn't care for. As for the music -you could find a nice variety throughout the ship. Again just one I didn't care for personally. We found the service in the windjammer hard to locate. You certainly couldn't count on getting a drink at your table. They seemed to be rotating the servers as we couldn't locate the same server twice in an area. This may be part of the problem.
We had a promenade view cabin.
We took the shuttle for $4 to town to walk around. The shopping was varied and the buildings interesting to see. We went to the Magic Ice attraction and it was a nice change on such a hot day. If you go definately get the gloves and poncho.
Old San Juan is nice to walk around and there is a free trolley that runs until 5pm. The Condado district is also fun and has shops and the casino to stop into.
