Hey there, Alejandra!
Welcome to the Disney Parks Moms Panel, and thanks for your great question. Your trip will be here before you know it, and I'm so excited for you and your family to
Get Your Ears On at the Happiest Place on Earth!
As currently listed on the official
Park Rules of permitted items, wagons are still not allowed at the Disneyland Resort theme parks. You are, however, allowed to bring a stroller that is no larger than 36" x 52" that is pushed and not pulled behind you. After talking to many Guests with multiple children, they say that the maneuverability of a standard stroller or double stroller is more conducive to the parks than a wagon you would use at home. You may even enjoy the freedom of two single strollers since sometimes children may want to experience different attractions with parents separately, and this will give you more freedom. There is convenient stroller parking outside all attractions and restaurants. I recommend putting an identifier on your stroller since many look alike when parked in a large area together. We keep some simple ribbons tied to our stroller handle which has helped us SO much when it comes to quickly identifying our stroller in a crowd.
I hope this helps, and please be sure to return if you have any other questions about planning your Disneyland Resort vacations. Have a Fantasmic day!
