Welcome, Clodeshmarie, to the Disney Parks Moms Panel!
I have good news for you regarding
stroller rentals at Walt Disney World Resort. When you rent a stroller at Epcot, Magic Kingdom Park, Disney's Hollywood Studios or Disney's Animal Kingdom, save your receipt. If you present that receipt later that same day at one of the other Disney theme parks, you will not need to pay an additional fee to use a stroller there. Thus, your child will get to test drive two (or more) Disney strollers in the same day.
Since you plan to visit the Disney theme parks for three days, you may want to consider doing a length of stay rental to save a few dollars. I'm so pleased that this option is now available to guests who are planning an extended stay.
Wishing you and your son or daughter a magical Walt Disney World Resort vacation,
Jill
