Hi Lisa,
Welcome back! Almost all of the Attractions at the
Walt Disney World Resort would be suitable for children of that age although some do have minimum height requirements in order to ride. If your children are over 48 inches tall, then they will be able to enjoy all of the Attractions at the Theme Parks. My kids are a mix of "thrill seekers" and "easy riders" so we always incorporate a little bit of both into our plans. Here are of my suggestions for your family:
Magic Kingdom Park:
Seven Dwarves Mine Train
Big Thunder Mountain Railroad
Pirates of The Caribbean
Disney's Hollywood Studios:
Star Tours® – The Adventures Continue
Rock 'n' Roller Coaster® Starring Aerosmith
Toy Story Midway Mania!
Epcot:
Soarin'®
Test Track
Living with the Land
Disney's Animal Kingdom Theme Park:
Kilimanjaro Safaris
Expedition Everest - Legend of the Forbidden Mountain®
DINOSAUR
Kali River Rapids®
If you are unable to secure
FastPass+ Reservations for these Attractions, then I recommend arriving before Park opening and then heading straight to your "must-do" Attractions as soon as the rope drops.
I hope these suggestions help you to make the most out of your Walt Disney World Resort vacation!
Magical Wishes,
Susan
