Hi Ashley! Welcome to planDisney!
You must be thrilled to visit the Walt Disney World Resort with your
little one in just a few more days! Vacationing with kids is such a magical experience as you watch their faces light up with wonder at all the
attractions, nighttime spectaculars, and familiar
Character sightings. These will be moments that you'll hold dear for years to come!
When
renting strollers in the theme parks, they cannot be reserved in advance. They are available on a first-come, first-served basis and are available to rent daily or as a length of stay rental. The length of stay option allows you to pay for your rental on the first day for all the days you are visiting, then you simply show your receipt to pick up a stroller on the following days. This doesn't reserve your stroller, though, as it is still subject to availability.
If you will need a stroller outside of the theme parks, you can consider renting from the Disney Features Provider, ScooterBug. This method of rental does let you reserve in advance, but you'll also have to take it with you to and from the theme parks each day.
I hope you have the BEST vacation, Ashley! Please let us know if you have any other questions.
