Welcome, Elizabeth!
I'm so glad you stopped by the Disney Parks Moms Panel with your question. It's a great idea to clarify if your stroller adheres to the
recently announced update of the Walt Disney World
Property Rules in advance of your visit.
Strollers must be no larger than 31" wide and 52" long. As you can imagine, with hundreds of brands and models of strollers on the market, and new products being introduced all the time, it would be an impossible task to keep an accurate list of approved strollers. It is up to the guest to be aware whether or not their stroller fits the guidelines. You can refer to the specifications for your particular stroller model as provided by the manufacturer, as well as measuring it. I recommend configuring your stroller as you intend to use it, and measuring the widest and longest points. An easy way to see if your stroller meets the guidelines is to box out the approved dimensions on the floor, and make sure your stroller fits entirely within the box, including wheels and handles.
If you find your stroller is too large, you might consider
renting a stroller. Single and double strollers are available to rent at all Theme Parks and
Disney Springs. The rental strollers are easy to push and easy for children to get in and out of. They are probably best suited for children who can walk, but need to rest their little legs from time to time. However, they are not padded and do not recline, so if you have an infant I would recommend renting from a Disney Featured Provider. These independent rental companies have several models of strollers to choose from, and will deliver a stroller right to your hotel.
I hope that helps! Please feel free to visit the Moms Panel again if you have any additional questions.
Have a wonderful visit!
