My wife and I just got back from our 7 night cruise. Overall we had a very good time. Embarkment took about an hour and we boarded the ship around noon. The ship itself was in great shape. I saw no significant flaws or worn parts as the last reviewer did. We had an inside cabin and this was adequate. The cabin was small but the spacing and organization of the room left us with adequate space and usability.
The ship was beautiful and offered a lot of activities. The shows in the night club were excellent. The coasters were booked for one night and they were a lot of fun. The ship was full for this cruise and it felt it. Even thought the ship is huge 3600 people got a bit crowded in the atrium and around the pool area. The food was fair. It wasn't bad but wasn't great. We have gone on Carnival a few times and I think their food overall was much better. The staff seemed in good spirits and we got excellent service overall.
Our first port was San Juan. We did a walking tour of the city and visited El Morro. The city was nice and we had a pleasant time. There is not much to do besides walking around and seeing the sites.
