Hi, Sarah!
Thanks for checking in with the Disney Parks Moms Panel!
Walt Disney World is all about helping kids get the wiggles out! There are playgrounds all over the Walt Disney World Resort property. So many, Disney Parks created
this map to help you find each and every one of them.
One of my favorite playgrounds at Magic Kingdom Park is a tiny one under the train station near Splash Mountain. I have memories of my kids playing there while bigger kids and grown ups would go on the "big kid" attractions in the area. A great wiggle release at Epcot is the playground on the path between Future World and the World Showcase that leads you to Canada.
I am not aware of a playground in Disney Springs. But there is a "Lego Playground" at the Lego Store and there are a couple of spots where there is a water spray area for kids to enjoy. There's also live music scattered around the shopping area that gives us all a chance to shake a groove!
I hope that helps with your planning! Have a fantastic visit! Your vacation starts soon!
