The whole park of MGM Studios is good for teens. There they have the ever popular Tower of Terror, Rock 'n' Roller coaster, a whole bunch of shows, and alot of cool places to eat and shop. Down Town Disney also has a bunch of teen stuff, shops, no rides, and resturaunts. Magic Kingdom has a few teen-friendly things, but mostly kiddy things, but if you have park-hoppers, you should stop by. It is just so magical, and you might want to ride the mountains. At Epcot, there is alot of walking involved, but alot of neat seanery, and three rides. Animal kingdom is just like a bug zoo, with setions devoted to Africa, Asia, Dinosaurs etc. They do have a few cool rides, including Dinosaur. My family has not been there for so longg, because we only have limited amounts of vacation time, and to us, it is not worth it.
I hope this helped, and have fun.
