chEARs Brent,
Welcome to the Disney Parks Moms Panel. What lucky grandkids you have! I love that you are
sharing magical memories with the next generation of your family, and I completely empathize with the need for a wagon to carry tired kiddos! Just a few yEARs ago, I had three under three, and our stroller was my life-saver in the Parks!
As you know, Disneyland Resort
modified it's stroller guidelines in the Spring. Now, strollers must fit
specific dimensions, and wagons are not allowed in the Parks. The change is so that all the Resort Guests can have a magical experience. But! You are more than welcome to use a wagon to carry the kiddos to and from the carpark; you will just need to rent a locker to store it outside. My dEAR friend, Anabel, laid out all of the locker dimensions
here. Just make sure that your wagon (when broken down) can fit!
Brent, if you park in the Mickey & Friends parking structure, there is
a super convenient tram that will take you to
Downtown Disney District, which is steps away from both Park entrances. It is complimentary and totally fun. I bet your grandkids would get a kick out of riding it, and that might save you a locker rental! The same holds for the
Pixar Pals parking - it shares the complimentary shuttle. Also, if you still want to use the wagon, Pixar Pals has a Magic Way Pedestrian Bridge that connects the garage with the rest of the Resort.
I wish you a "wheely" fun visit!
