Hi there Rosa,
Welcome to planDisney and thanks so much for stopping by with your question! I'm thrilled to hear you and your family will be making new magical memories at the Happiest Place on Earth next month!
It sounds like you might have learned about the
Disability Access Service (DAS), which is a service for Guests who, due to a developmental disability like autism or similar, are unable to wait in a conventional queue for an extended period of time. To request this service, you will need to either live video chat with a Cast Member or speak with a Cast Member at an Accessibility Services Kiosk while on-site.
Once registered and on-site for your visit, you'll be able to make attraction return time selections through the Disneyland mobile app or with a Cast Member at the Accessibility Services Kiosks.
Additionally, there is a wealth of helpful information on the
Accessibility hub on the Disneyland Resort website including planning guides and recommendations sheets to help you and your son have a fun and smooth experience during your visit.
Thanks again for stopping by with your question, Rosa! I hope you have a great time on your trip.
Have a Magical Day,
Greg
