Hi Jaclyn! I'm so glad you stopped by the Disney Parks Moms Panel for clarification on your question about wagons.
Wagons of any kind, whether pushed or pulled, foldable or otherwise, are not permitted at any Walt Disney World theme park or water park.
You may have heard about an
announcement regarding
recent updates to the
Walt Disney World Property Rules. Included in the announcement was a reminder that wagons are not permitted, and clarified that this does include "stroller wagons".
You are welcome to bring your own stroller, provided it is no larger than 31 inches wide x 52 inches long. If you would prefer, single and double strollers are also available to rent at all theme parks and Disney Springs. Disney has also partnered with Featured Providers, who can drop off a rental stroller directly to your Disney Resort Hotel. How's that for convenience? Contact information for the Disney Featured Providers is provided on this
Stroller Rental page.
I hope that helps! Please feel free to visit the Moms Panel again with any additional questions you may have. Enjoy your visit!
Anne Marie
