Hi Brittani!
Welcome to planDisney! Thank you for sending this question to us hEAR. Oh Boy! It sounds like you'll be enjoying some Disney Days with your very own Mouseketeer! You'll for sure want to stop by the
Baby Care Centers for all of your baby and toddler needs, from emergency items you might need to purchase to tiny toilets for those who are potty training.
Wagons and Stroller Wagons are
not permitted at Disneyland Resort. (However, you may see one from time to time being used as a medical device by some of Mickey's most exceptional friends.) The good news, Brittani, is that there are plenty of other
stroller models that can fit multiple children, have plenty of shade, large storage compartments, and anything you need, really, that still comply with the size requirements of being under 31" (79cm) wide and 52" (132cm) long. I've personally used a double Bob jogging stroller and an UppaBaby Vista in 3-kid mode and they were both good-to-go. And feel free to bring the add-on attachments like saddlebags and rain or cold-weather covers. I've even brought those large carabiner clips before and attached a tote bag to the back handle of mine so I'd have another storage area. But heads up, security will need to double-check everything on your stroller, so it's best to wait to attach everything until you're through the screening.
There are also
strollers available for rent, Brittani, should you not want to bring yours or you'd like to wait and see if you'll need one. The Disney rental strollers, available next to the
Picnic Area, push and turn like a dream and are perfect for older (and tall!) kids who can walk but maybe not for a whole Disney day. I will say that they are made out of hard plastic, so bringing a blanket just for the stroller isn't a terrible idea. Another idea is to rent a stroller from Disney's Featured Provider Scooterbug.
I hope that this helped to plan your upcoming Disneyland Resort Vacation a bit better, Brittani. And If you have any more questions about Disneyland's theme parks, hotels, dining reservations, attractions, kiddo-prep, or anything, We're All Ears!
