I was signed up to go on it this past Halloween cruise, but not enough people were going.
I agree that a teen should be comfortable with making new friends and opening up to people. On my first cruise I didn't have much fun cus there were so many cliques, but the second cruise I had a lot more fun cus I met someone on DIS who was going too! It also depends on the counselors. The first cruise they sort of joined in on the cliques, but the second one they paid attention to everyone.
I say go for it. The teen junkaroo should be a blast!
