Hello Amie!
Welcome to planDisney! I'm so glad that you were able to register for DAS Advance, I hope that it helps you and your group to have a great experience in the parks.
Disability Access Service is such an amazing program! It's great that you've already made your
DAS Advance selections. You are a heroic park planner already! Your DAS Advance return times are separate from your regular DAS return times that you will select when you enter the parks. Just keep an eye on the clock so you don't miss your DAS Advance time slots!
You'll be able to make same-day DAS selections right in the
Disneyland Mobile App! When you've entered the park just open the app, sign in, and tap the "☰" icon (bottom right side of the screen) to open the main menu. You should be able to see a Disability Access Service (DAS) button since you've already registered for the program. Tap the button and you'll be able to select a return time for an attraction. Once you've used that return time you'll be ready to choose a new one!
If you have any issues you're always welcome to stop by the nearest guest services location, there are plenty of them! Just open the map section of the Disneyland Mobile App and tap the menu at the top to choose "Guest Services" to see the closest location.
One of the best resources for guests visiting the parks with disabilities is the
Guide for Guests with Cognitive Disabilities. It has some great information about what to expect during your park day, as well as ideas for quiet spots to take a break. Super helpful!
Thanks again for your question, Amie! I hope your group has a practically perfect day at the Disneyland Resort!
Keep moving forward!
Amanda
