Hi there Stephanie, welcome to planDisney! We're so glad you're here!
You are correct that
wagons and stroller wagons are not permitted at the
Disneyland Resort. Unfortunately, you will not be able to bring a wagon through security at the entrance into the
Downtown Disney District or either theme park.
I definitely understand the need to bring essentials with you for a long day of fun in the parks, so I wanted to share a few options with you. There are
lockers for rental in the Esplanade outside the Main Entrances to both
Disneyland Park and
Disney California Adventure Park, and there are a few jumbo-sized lockers for rental that can hold a ton! There are also lockers right inside each theme park after you scan your tickets for entry. This could be a great option if you have items you want to bring with you but do not want to carry around all day.
You also could bring a stroller, especially if you have little ones! Strollers brought from home are welcome as long as they are not larger than 31" x 52". We store a ton in our stroller all day, from snacks and water to sweatshirts for those cool California evenings.
I hope this information is helpful for your upcoming trip Stephanie! If we can assist with anything else, please do not hesitate to
come back and ask!
Have a magical day!
Melissa
