After entering a park, open the My Disney Experience app and sign in to your Disney account. Tap the More  option at the bottom right of the welcome screen. Then, tap on the Disability Access Service (DAS) button to enter the self-selection flow. The tool can also be accessed from attraction detail screens.

DAS is intended for Guests who have difficulty tolerating extended waits in a conventional queue environment due to a disability. DAS doesn't provide immediate access to experiences, but rather allows Guests to request a return time for a specific experience that is comparable to the current standby wait.
