Hi Sara,
Thank you for submitting your question to the Disney Parks Moms Panel!
Traveling with little ones to the park is challenging, especially when it comes to choosing which park is the most accommodating for them. I too have a daughter (she just turned 3) and it is very important for me to make sure I take her interests into account when visiting the Disney Parks. All of the Disney Parks have attractions and entertainment for toddlers, but believe it or not, I would recommend
Disney's Hollywood Studios over Epcot and Disney's Animal Kingdom! The reason is that Disney's Hollywood Studios features several attractions my daughter loves:
Disney Junior - Live on Stage! Show (which features Mickey Mouse Clubhouse, Handy Manny, and other loveable Disney Junior Characters);
Voyage of the Little Mermaid (which features a real life Ariel); and the
Beauty and the Beast-Live on Stage Show. I am sure she will also love Pixar Place where she will be able to step inside of Andy's Room (Toy Story) and ride Toy Story Mania! Let me not forget to mention all of the
character meet and greets throughout the park!
Hope this helps! If I can assist you with any other planning question, please feel free to ask!
Yael
