Hello there, Alexis! Welcome to planDisney. You've brought us a great planning question for your upcoming visit.
The stroller rentals are such a wonderful offering at Disneyland Resort for traveling families. It's just one less thing to travel with and worry about. I am happy to share that
stroller rentals are always available rain or shine. They are first come, first served, so it is ideal that you show up and get that rented first thing of the day. They have both single and double stroller options available for rent. You will have a slip of paper placed in the stroller pocket that shows your last name so you can identify your stroller. I always recommend buying a balloon in the parks or bringing some fun decor to decorate the stroller so it's super easy to find it when you park it to go onto an attraction. The stroller rental area is easy to find just to the right of the main entrance gates of Disneyland Park if you are looking at the park entrance.
Since it sounds like you are heading to the park with one or a few little Mouseketeers, don't miss out on
Mickey's Toontown. There is so much to see and explore there and it's a great place to get some of those wiggles out!
Alexis, I hope you have a magical visit to Disneyland Resort. We are always here for all of your planning questions!
