It's great to see you here today at planDisney, William! I'm so glad to be able to answer your question. There is so much ground to cover at Walt Disney World Resort, my family and I average about 10 miles of walking every day, so it's a great idea to plan for how the
younger Mouseketeers in your party are going to get around.
According to the
Resort Property Rules, Policies, and Regulations, stroller wagons are prohibited at Walt Disney World Resort. Even if your stroller wagon fits within the acceptable dimensions for a stroller, it will not be permitted inside the Theme Parks as a safety precaution. You are welcome to bring your favorite single or double stroller, provided that it is less than 31" (79 cm) in width and 52" (132 cm) in length, or you can
rent one at any of the Theme Parks or from a Disney Featured Provider for the length of your stay. It is possible that you may see stroller wagons on your upcoming trip to Walt Disney World Resort because, under certain circumstances, they can be approved as mobility devices for guests with disabilities.
William, if you plan on bringing a stroller from home, I recommend using masking tape to create a box on your floor that is 31" (79 cm) in width and 52" (132 cm) in length. If your stroller fits within those markings, you're good to go! This is the same way that security will double-check your stroller if they need to, so it's the best way to ease your mind and make sure that your stroller is the appropriate size before you leave for your trip.
Have a magical day, William!
