Hey there Sabrina,
Welcome to planDisney and thank you so much for the opportunity to help you as you're planning your upcoming trip with your Mouseketeer!
According to the
prohibited items page on the Disneyland Resort website, stroller wagons are not permitted into the parks.
However, the Disneyland Resort is committed to providing a welcoming, inclusive environment and accessible experience for Guests, and they offer the
Disability Access Service (DAS) for people who need a bit of extra support in accommodating their trips to the Happiest Place on Earth.
While those stroller wagons are not permitted, there might be other accommodations that a Cast Member could help with through DAS to help make your trip magical! My suggestion would be to pre-register for the service through
DAS Advance so you can talk about the specifics of your situation with a Cast Member through a video chat to see what your options might be.
The DAS Advance planning option is available as early as 30 days but no less than 2 days prior to arrival, so it looks like you should be in that pre-registration window now. I've also found the
Services for Guests with Disabilities page to be a helpful resource as well as you continue to plan your trip.
During your visit, I would also recommend highly prioritizing a visit to
Mickey's Toontown. This land was recently reimagined and opened back up earlier this year with so much more to explore for little ones of all abilities. One "secret" I found was a special sensory green area in the back corner of the land where there are shaded, quiet areas to take a break.
Thanks again for your question, Sabrina! I hope you have a fantastic visit to the Disneyland Resort!
Have a Magical Day,
Greg
