I sailed on Adventure of the Seas in June 2004. It was my 5th cruise. I had sailed RCCL before and wasn't at all impressed and vowed never to sail RCCL again. However, our kids ages 11-15 wanted to go again because of the Royal Promenade. They liked meeting with other kids.
Another disappointment was the food. It was absolutely the worst food I have ever put in my mouth. The steak was so thick and tough my knife wouldn't even cut it, The chicken was like hard rubber, and the desserts were tasteless. They only had one salad a night and if you didn't like it they would bring you some lettuce with tomato on it. The dressing of the night is what you got regardless whether you liked it or not. I lost one pound while on the cruise. I must say though, the dining service was great.
The shows were bad. My granddaughter's dance team is better than those dancers. In fact that is what the 2 nights of dancing was, dance team quality. The 2 comedians were not funny and had a filthy mouths. Not suitable for families.
