As you know the Fantasy ship is the oldest in the fleet but it has been updated. It took awhile to get the hang of the layout but we tried out almost all the areas and activities provided. (We didn't use the spa or gym-not our thing.) Most of the entertainment was not fancy but it was FUN. There was only 1 male singer that we just didn't like but there were two particular bands that we really enjoyed.
The food was plentiful with 24 hour availability of pizza and soft serve ice cream. The dining room (Jubliee) decor wasn't wonderful but the service was GREAT and fun. We tried to eat at each of the dining stations but couldn't get it all in. We enjoyed trying lots of different kinds of food. It wasn't the best cruise food ship but we all ate plenty. The bread is especially good:)
The only real negative was how the smoke traveled from the casino into the other lounge areas. The ship appears to be mostly non-smoking but it isn't very well enforced. I would recommend this ship for families with children. My kids really enjoyed their kid club time, lots of dancing, music, and unlimited food.
