Welcome to the Disney Parks Moms Panel, Ashley!
Strollers are available for rent near the entrance of Disneyland Park. At this time, prices for stroller rentals are:
$15 per day for one stroller
$25 per day for two strollers
I have also found a great off-site company, City Stroller Rentals, where Guests can rent strollers and other baby equipment. You reserve your stroller online (you can choose different styles, single or double strollers) and the company will deliver to the bell desk of your Disneyland Resort or Good Neighbor Hotel when you arrive.
I hope this information will help you decide whether to rent or bring your own stroller. Please visit me on the Panel if you have further questions! I wish you and your family an unforgettable trip to the Happiest Place on Earth, Ashley.
Have a magical day,
Kiki
