Walt Disney World guests can register to audition in front of a Disney casting director for a chance to take part in the theme park show. Contestants who make the cut must then audition for a Disney producer. Those selected by producers will perform in front of an onstage panel of judges and an audience of park guests who vote on each show's winners.

Performing guests with the highest votes compete in an end-of-day grand finale show at the attraction. The winner of that competition gets a guaranteed reservation, with no waiting in long lines, for a future regional audition for the real "American Idol" TV show.
