Hi Rhonda!
It sounds like you are
getting ready for a fantastic Walt Disney World Resort vacation with little ones and I'm glad you are planning ahead for your little one's stroller! You will travel many miles through the Walt Disney World Resort theme parks, so it's definitely important to have a place for your little ones to rest their legs during your day. In my family's experience, a comfy stroller ensures my little ones have plenty of energy for the entire day, allowing all of us to even enjoy the nighttime entertainment in the theme parks!
Guests can
rent strollers from each of the theme parks and
Disney Springs to use during their visit. You cannot rent strollers in advance, so simply head to the Stroller Rental locations at each of the theme park entrances and Disney Springs to secure your rental stroller. In my experience, there have always been plenty of strollers available every time I have visited, so I would recommend that you don't need to be too concerned about strollers being unavailable.
You also have the option of
renting a stroller from one of the Disney Featured Providers, which you can secure in advance if you would prefer to reserve your rental prior to your trip. Personally, my family likes to use the Disney rental strollers as they have plenty of room for my little ones' long legs!
Let us know if you have any additional questions as your trip approaches. T-T-F-N, ta ta for now!
