Greetings Larry!
Welcome to planDisney! Thanks so much for bringing a question our way!
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) and wagons, including stroller wagons, are not permitted. So, you will not be allowed to bring your wagon with you.
But,
Stroller Rentals are available outside the Disneyland Park Main Entrance adjacent to the Kennel and at the
Pixar Pals Parking Structure. 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 that you tie an identifying object on the handle that will make your stroller stand out from the rest! An iconic Mickey balloon should do the trick!
Please head back to planDisney if you think of any other questions we can answer for you.
