Hey Howdy Hey Veronica and welcome to planDisney!
Your vacation is just a few weeks away and I'm sure the excitement has gotten to you of all the Magical experiences that are waiting for you! Thank you for stopping by with your question about stroller rentals, let's go over the details so you will be ready to go.
Stroller rentals at the Walt Disney World Resort can come in a few varieties. Disney does offer stroller rentals for your time in the parks. You can get a single or double and you can pay per day or for the duration of your stay. Rentals are on a first-come, first-served basis and cannot be made in advance. I have yet to hear of a time when Disney ran out of strollers so I would not get too worried about it!
If you do think you would need a stroller outside of the park as well, you can look into a third-party company for rentals. ScooterBug is the Disney Featured Provider and they can rent single or double strollers for you as well. These strollers would be yours for the entire time of your validation dates and can be picked up and dropped off at all Disney Resort hotels and many offsites as well. In my opinion, the City Minni strollers that most third-party companies rent are a lot nicer to maneuver in the parks and more comfortable for the kids. These have been strollers we use for the duration of our vacations and find it very easy to navigate the parks and Disney resort transportation when necessary.
I hope this helps clarify your options but if you have any other questions let us know, we are always happy to help!
To Infinity and Beyond,
Nick
