Hi Marci!
Welcome to planDisney! Thank you for bringing your question to us!
Guests are permitted to bring strollers to the Disneyland Resort as long as they fit within the
stroller size guidelines.
Disneyland Resort Rules state that strollers must not be larger than 31" (79 cm) x 52" (132 cm). The rules also state that wagons, including stroller wagons, are not permitted. So, you will not be permitted to bring that stroller as it falls outside of those guidelines.
Please note that Stroller Rentals are available. You can find
Stroller Rentals outside the Disneyland Park Main Entrance adjacent to the
Kennel. Strollers are rented on a first come first served basis, so if you prefer to rent a stroller, be sure to arrive early. Rental strollers can be hard to distinguish in a sea of strollers. I recommend fastening something to the handle that will make it stand out from the rest! An iconic Mickey balloon should do the trick!
I hope this answers your question! Please head back to planDisney if you think of any other questions prior to your magical vacation.
