Epcot:
Fastpass:
Soarin'
Maelstrom
Turtle Talk With Crush
Also ride on standby or with additional fastpasses:
Living with the Land (it was one of my daughter's favorite rides when she was 5; in fact, it still is one of her favorites--that & Expedition Everest, go figure); I wouldn't fastpass Living with the Land as you won't need a fastpass for it, but I would definitely do the ride
The Seas with Nemo and Friends (another favorite of my daughter; won't need a fp though)
DHS:
Fastpass:
Toy Story Midway Mania
If your child is adventurous: Tower of Terror & Star Tours
Also ride on standby or additional fastpasses:
Voyage of the Little Mermaid
Great Movie Ride (another favorite of my 5 year old; beware there is an alien part that can freak some kids out; mine wasn't phased by it; I was prepared to hide her eyes, but she wanted to see. When my oldest daughter was younger, I covered her eyes on the alien section)
Beauty and the Beast show
