DD11 likes pretty much everything at WDW. The only ride she doesn't care for is Dinosaur (it's a volume thing).
While the thrill rides are great (and DD loves them!), if this is a first trip, be sure and include the other WDW experiences as well. A lot of people have the misconception that meeting the characters is for kids but we have found that the character experience is actually enhanced as kids get older and the characters can have more fun with them without scaring them/ hurting feelings. We had especially good interaction with Gaston, Dug & Russell, Goofy, Minnie, Merida, Fairies (it's just Tink now), Ariel, Belle, Jasmine and Aladdin on our last trip.
In addition to character meets, DD's must do's are:
MK: All the mountains, Haunted Mansion, Mickey's Philharmagic, Winnie the Pooh, Small World
Epcot: Test Track, Soarin, Mission Space, Living with the Land, Spaceship Earth, Nemo ride, eating around World Showcase
Animal Kingdom: Expedition Everest, Kali River Rapids, the Safari and Maharajah Jungle Trek
DHS: Tower of Terror, Toy Story Mania
She also loves the night time shows/ parades, though we don't fit them all in each trip.
