There are dozens of rides and attractions at Walt Disney World that are appropriate for preschoolers.
You can take your two-year-old with you on any ride for which there is no height requirement.
If you look at this page of travel tips for people with small children found
HERE,
you will see a button on the right hand side of the page that says
"Height Requirements." Clicking on this link will bring you to handy
pdf that you can download. The pdf lists the attractions in all four
theme parks and both water parks that have height requirements.
If an
attraction is not listed on this document it means that there is no
height requirement and any age child can enjoy the ride.
If you're looking for suggestions, most preschoolers are captivated by colors and sounds on the Small World
ride and the Many Adventures of Winnie the Pooh. Other great attractions for this age include the Carousel, Peter Pan, the Jungle
Cruise, the Magic Carpet of Aladdin, Buzz Lightyear, Mickey's Philharmagic, and many more.
Have a great vacation with your family!
