Hi, Marisa!
Renting a stroller is a great idea. You can easily walk several miles in a single day, so hopping into a buggy can certainly be helpful for our little Mouseketeers.
You are welcome to bring your own stroller from home or
rentals are available at each of the theme parks. The stroller rentals are near the entrance of the parks. There is a daily rental fee, and a small discount if you purchase a multi-day rental. If you take a mid-day break, you can get another stroller without paying again. Simply show your receipt to get another set of wheels! Strollers must remain in the parks, so drop off your rental as you depart the main gates each day.
If you choose to bring a stroller from home, be prepared to collapse your stroller on parking lot trams and Disney buses. The advantage of bringing your own from home is that you can have your stroller around the resort and at the airport. And, of course, you can avoid the rental cost!
Have fun "wheeling" around Walt Disney World with your little one!
