Hi Erica!
Welcome to the Disney Parks Moms Panel. As the mom to two little boys, I have pushed strollers around Walt Disney World Resort over countless miles during our family trips. The strollers available for rent at the
Walt Disney World Resort Stroller Rental locations are perfect for little ones to rest their legs (and sometimes their eyes, too!) during a busy theme park day. Unfortunately, Guests cannot reserve strollers in advance from Stroller Rental locations. You can reserve a stroller in advance from one of third party rental locations, in which case I recommend that you use one of the
Disney Featured Providers. If you are renting from a third party, your stroller will be delivered to your hotel for you to use for the duration of your trip.
While your stroller cannot be reserved in advance or guaranteed, each of the theme parks do have a very large number of strollers available for Guests to use and they are able to support even the busiest of days. I've actually never experienced a Stroller Rental location running out of strollers for Guests to rent. So if you are planning on arriving at the theme park in the morning and if you aren't traveling on the very busiest of days, based on my experience I think you will be able to successfully rent a stroller for your magical day.
Please let us know if you have any additional questions! T-T-F-N, ta ta for now!
