Hiya Alejandra!
Thank you so much for your question! The great thing about Walt Disney World is that a large portion of the attractions do not have height restrictions, so your 2 year old will be able to ride with you on most of them! Our kids (at age 2) were very much into music, and color, and dancing any moment they could!
Walt Disney World with little ones is so much fun!
If your 2 year old is any familiar with the Disney Junior shows, you'll really want to make sure you catch Disney Junior - Live On Stage! at Disney's Hollywood Studios! It's a fun show, lots of fun: singing, dancing, audience interaction--it's a really good time!
At Magic Kingdom Park, your little one will have tons of fun in Fantasyland! There's so much to see and do there, and I can tell you the play area before you ride Dumbo the Flying Elephant will be a huge hit with your 2 year old! The great thing about this age is they don't need anything extravagant. They find joy in the smallest moments. It's one of my favorite ages to witness discovery and play...and truly...as long as they're fed and content...everything's magical!
At Epcot, The Seas with Nemo & Friends will likely be a great hit if they love fish! My kids could never get enough! We would ride and chase fish practically all day. Those little feet walking miles and miles 'under the sea.'
Disney's Animal Kingdom Theme Park is great for watching animals as well as exploring music. We spent quite a bit of time here roaming, dancing, and exploring. TriceraTop Spin is a fun ride for the little ones, and we've spent many hours in The Boneyard digging and exploring.
Have a magical vacation!
