Typhoon Lagoon has an amazing wave pool and Blizzard Beach has Summit Plummet if you plan to visit water parks.
There are lots of golf courses: par 3, regulation and miniature if they like golf. You can go fishing at several resort hotels. You can rent several different water sport vehicles and go parasailing at Sammy Duvall's. And don't forget utilizing some buffet meals for the never ending teenage boy appetite! My favorites include Boma and 'Ohana.
