I hope you get this before your trip. I have one piece of advice for your teen, go to the teen events and make some friends day one. My son, who was 17 on our first Disney Cruise waited until day 3 to really make an effort to meet anyone. Before then he hated the trip. After that he had a wonderful time. He was sorry he wasted those first few days. He still corresponds with some of those kids three years later.
