Hey Ashley!
There is SO much for a two year old to do at Walt Disney World!!!! Since I have five children under the age of 10, I can tell you from experience that Disney really takes care of families with small children!
To begin, Disney World has put together an incredible tool right
HERE to help begin your planning process!
These are the attractions and shows my children loved at the age of two:
Magic Kingdom - All of Fantasyland, Buzz Lightyear's Space Ranger Spin, Mickey's PhilharMagic, and Wishes Nighttime Spectacular.
Hollywood Studios - Toy Story Mania!, Disney Junior - Live on Stage, Beauty and the Beast - Live on Stage, and Voyage of the Little Mermaid.
EPCOT - The Seas with Nemo and Friends, Spaceship Earth, and Journey Into Imagination with Figment.
Animal Kingdom - Kilimanjaro Safaris, Finding Nemo - The Musical, and Festival of the Lion King.
I hope this helps you in your planning! If you have other questions, please let me know!
Have a MAGICAL day!
