Hello and welcome to the Disney Parks Moms Panel!
I loved reading that you and your family are currently planning for a Walt Disney World vacation! You have posed a great question, so let's get started so that the planning can continue.
Unfortunately, wagons of any kind are not permitted in the Disney Theme Parks. You may view the
restricted personal items page by clicking on the provided link. However, you may rent
strollers for your little ones at any one of the four parks.
Diane's Tip of the day: I highly recommend placing a bright colored ribbon or securing a balloon to your stroller. There will be a "river" of strollers and this simple task will help yours stand out among the rest.
Have a MAGICAL day and "SEE YOU REAL SOON!"
