Hi Jana,
Thanks so much for bringing us this really important question. As the mama of a Mouseketeer on the autism spectrum, I'm happy to share how the
Disability Access Service works to help put your mind at ease!
When you first arrive, you'll want to visit a Guest Services location that's inside a theme park with your entire party. You will need to share your concerns about your daughter's difficulties waiting in traditional queues so that the Cast Member can set up the service for you. While they will ask to take her photograph, she really won't need to do much else at that point. The great news is that after that point, she won't need to hear anything mentioned about it again. It is all managed digitally now, so you'll simply need your MagicBands or cards to activate and use the service. To activate it, any member of your party may simply ask a Cast Member at an attraction entrance to use the service. They'll scan your MagicBand or card and give you a return time. When you return, you'll just need to make sure that your daughter scans first because the other members of your party won't be able to enter until after a Cast Member clicks a button to approve her return time. The only time my family has ever had a Cast Member verbally say something is if they're asking us to use both FastPass+ touch points. We simply smile and say, "We can't until our prince goes first!" They can check their computer to confirm, then we can all scan and enjoy! I'd encourage you to come up with some language like that to use in case you do need to discuss anything in front of your daughter. Most of the time, though, nothing will ever need to be said. It's truly a wonderful service for kiddos like ours who otherwise might not be able to enjoy the attractions.
Have a truly magical vacation, Jana!
