Hi Patty!
Thanks for coming by to see us at the Disney Parks Moms Panel. Per the
Walt Disney World Resort Park Rules and Regulations, wagons are prohibited from the Walt Disney World Resort theme parks. Also prohibited are any other trailer-like items that can be pushed or pulled from a wheelchair, Electronic Conveyance Vehicle, or Stroller. So unfortunately, you will not be able to bring a wagon into the theme parks.
I have travelled many miles in each of the theme parks, both with kids and without. I like to carry a backpack with comfortable straps and pockets for water bottles. You can also bring a cooler into the theme park, if you would like to keep food or drinks cool. Your backpacks or coolers can even have wheels. Keep in mind that your backpack or coolers need to be smaller than 24" long x 15" wide x 18" high.
For transporting kids, I recommend using a stroller or double stroller to get around the theme parks. I have brought my own double stroller for trips and
rented a stroller for other trips and both options have worked well. Most importantly, your stroller should be comfortable to push around the theme parks. Plus, you can use your the extra space in your stroller to carry bags and souvenEARs during your day!
Please let us know if you have any other questions! T-T-F-N, ta ta for now!
