There were 10 of us that went together including two 14 year olds, a 16 year old and a 18 year old.  They all had a great time.  The two 14 year olds, loved the kids clubs, it kept then busy, and they were able to meet and greet other kids of the same age. They danced, ate etc and i never  had to worry about any of them.  The two other teens enjoyed themselves also by keeping themselve occupied by just hanging out and me not having to worry about them getting any alcohol.  I really felt safe on board.  The room attendants did a great job.  I think better than a Hotel service could be.  The entertainment was somewhat ok, loved the adult comedians, shore excursions way to high in price, but overall, we had no mishaps, good service and a well relaxing cruise.  I will always recommend Carnival to friends.  The ship is cheap and affordable.  If i was on the Queen Mary of course i would expect more from the ship.   Looking at another cruise sometime in near future.
