Hello Teen mom:
I am also cruising with a teen (14) year old son, and I've got quite a bit of info on activities for them. My concern is the same as yours because teen boys can be hard to please sometimes
We cruise on 11/30. Can't wait!
I'm not sure which cruise you are taking, but on the 4 day. We have a full day at Castaway Cay and they have a teen activity called "The Wildside." They will go kayaking, biking and snorkling. This cost $35. They also have a teen cruise that takes them around Paradise Island in Nassau its a party for teens ages 13-17. They have a hang out spot called "Common Grounds" on the ship that closes around 2:00a.m they should have alot of fun there. The teen coaches organize activites, games, and contest. Common Grounds is a must for teens because apparently this is were all there activities get started. Theres an arcade room on the ship and an internet cafe that they can also be a part of, if I'm correct they do charge additional fees for the arcade and internet use.
Theres quite a few new disney movies that will be shown there that have not reached the box office yet. We plan to see Haunted Mansion. I hear they will also show Spy Kid 3D, Pirates of the Caribbean and a few others. I think the key is the'll have to get out and meet people. Your boys can hang out together. My son is going alone, he's a people person so I'm sure he'll have a good time!
Hope you guys have fun, if you find out anything more for them, please inform me....
