Hi, Jacqueline!
There are so many fun things to see and do at both Epcot and Disney's Hollywood Studios that I can see why you're having a hard time deciding which one to visit with your little girl. I'm leaning more towards Hollywood Studios simply because of all the Disney Junior interaction she could potentially have there! Let's map it out a little.
There is a really fun
free activity for little ones at Epcot called
Kidcot Fun Stops where you can pick up a complimentary cardboard Duffy the Disney Bear that your daughter can color with the supplies at each station. You then take that Duffy to each of the 11 Kidcot Fun Stops around the World Showcase Pavilions where a Cast Member will give your daughter a stamp of Duffy in each country! It's a fun experience and I think your whole family will enjoy it!
If your daughter is a Disney Junior fan,
Disney's Hollywood Studios is the place to be! At
Disney Junior - Live on Stage!, you'll be able to see new favorites from the hit Disney Junior TV shows
Doc McStuffins,
Sofia the First and
Jake & the Neverland Pirates. I think you'll all have a blast at the
Disney Junior Dance Party as well! Be sure to grab a Times Guide on your way into the Park so you can arrive in plenty of time!
I sure hope this helps you decide, Jacqueline! Thanks for stopping by the Moms Panel with your question and please let us know if we can help with any others that you think of!
Have a Pixie Dusted vacation!
