Hi Randi,
My teens enjoy Disney's
Yacht and Beach Club Resorts because of Stormalong Bay, the wonderful 3 acre swimming pool. These Resorts are also located near the Boardwalk area, which has the ESPN Club (great fun if your son is a sports fan). In addition, this area is near Hollywood Studios, which tends to be a favorite Park for teens. My teens also like staying on the monorail. I'd show him the
Contemporary Resort and the
Polynesian to see if either of those appeal to him.
He will likely enjoy renting the Sea Raycer boats to zip along the waterways. If he likes video games, get him a ticket to
DisneyQuest. It offers 5 floors of interactive gaming fun.
Favorite attractions will likely be: Expedition Everest (Animal Kingdom), Rock 'n Rollercoaster and Tower of Terror (Hollywood Studios), Test Track and Mission Space (Epcot), Splash, Space and Thunder Mountains (Magic Kingdom). He may also like the "Lights, Motors, Action! Extreme Stunt Show at Hollywood Studios (my sons think it's very cool).
Hope this helps and have a wonderful vacation,
Kaylene
