Hi, Jane!
You only need to pay one time a day for
stroller rental, so if you take a mid-day break or hop to a different park, simply show your receipt to receive another stroller. When my kids were little, mid-day breaks were super important, so it was nice to drop off one stroller, and get a replacement when we returned for some evening magic!
If you kids are still in diapers, make sure to locate the
Baby Care Center located in each theme park. These Centers are super handy for changing and feeding little ones. You will also find a place for diaper changes in the restrooms, but I always preferred the lovely air conditioned Baby Care Centers that feel like home with TVs, high chairs, rocking chairs, and even a kitchen. This is also the "go to" place if you need to purchase baby food, diapers, and other baby necessities.
Wishing you and your
little Mouseketeer a magical visit to Walt Disney World!
