This was my first cruise, so I don't have anything to compare this ship to. Embarkation was fast for me. The food was decent. I didn't eat as much as I thought I would. I think the heat suppressed my appetite a little.
I enjoyed the cafe, bars, comedy shows, casino, and parties. The shows in the theater were good. Most of the staff was very friendly.
I think I will enjoy smaller to mid sized ships, and I didn't get seasick at all. The rocking was soothing at night, and it added to my experience of really realizing "Hey, I'm on a ship in the middle of the ocean!" Plus, I enjoyed the spots on the ship where you could just sit alone and relax for a while. I don't imagine the ships with 5k people have many quiet public spaces.
My suitcase arrived on time and my room was very clean. I did not experience any sewer odors like some mentioned before. I was on the forward Upper deck (interior), and I definitely felt the ship rocking. It didn't bother me.
Very cute city and I got some good souvenirs. There is a CVS in Key West, so take a trip there for last minute things you forgot. We were only there for 3-4 hours, so I just walked around.
