Hello, Carl!
My family loves meeting our favorite characters during our visits to the Walt Disney World Resort. I believe you are inquiring about using the FastPass+ system to reserve a time to meet beloved characters.
FastPass+ is a complimentary service included with valid theme park admission that allows Guests to schedule three experiences per day prior to their arrival based on their choices and available times. The experiences might be an attraction, show or character meeting, and allow Guests a one-hour window to visit. FastPass+ experiences are listed in
My Disney Experience (web and mobile app) and noted by a blue circle with FP inside.
Most of the popular characters offer FastPasses, and you will find most have a
Disney PhotoPass Service photographer present so that all of your family members are in the photo. It's important to note that not all characters offer FastPasses. Some characters have regularly scheduled appearances while others tend to be more random so check your My Disney Experience account for locations, times and appearances.
Thanks for visiting the Disney Parks Moms Panel, and please let us know if we can be of further assistance!
Have a magical day!
