Hello, Mandana! Welcome to planDisney. It's a pleasure to have you sail to us with your question.
I have great news, as you do not need to register or book your teenage sons for the youth clubs on board. On embarkation day, they can visit
Edge (the club for tweens ages 11-14) and
Vibe (for teens ages 14-17) to see the spaces, get to know the counselors, and meet cruisers their own ages. These spaces are designed with teenagers in mind, with games and activities tailored just for them. They can come and go as they please and decide what they'd like to participate in. I hope they have a blast together.
The Disney Magic has the perfect waterslide for teens, the
AquaDunk. It's a seriously thrilling plunge, and I hope they give it a go. It's fun for anyone brave enough to try! After the fun on the pool deck, I'm guessing your sons will be up for some nearby refreshment, and soft-serve ice cream cones are my recommendation. An ice cream break on a Disney Cruise is always a great idea.
Please return to planDisney if you have more questions. My pals and I will be here to help you!
Happy Sailing,
Adrianna
