I'm 16 and I went on the Carnival Victory Cruise on Jan 20-27. I had the best time of my life. There wasn't too many other teens-but enough to have fun. There is a Club Arctic-they play very good music. Depending on your age, the teen dance is from 9-10, but not too many people go to that, and then for adults after 110-if you are over 16 you can go into it and meet people, and dance its really great.
The excursions to bad for my family (of 6) They were quite organized and very very fun!
And there are lots of activities going on too. A schedule willl be brought to your room saying what all is going on where for that day-very helpful!
The food! its great-a 24-hour pizza place(i lived there, lol) And many more food places, Which is all free! And i didn't think it took long at all. And if you get a fountain card-you get free soda the whole week too!
But thats what i have to say-if you have any other questions, i'd be glad to try and help!
