Disney Fastpass is a virtual queuing system created by the Walt Disney Company. First introduced in late 1999 (though the idea of a ride reservation system was first introduced in world fairs), Fastpass allows guests to avoid long lines at the attractions on which the system is installed, freeing them to enjoy other attractions during their wait. The service is available at no additional charge to all park guests.

Each attraction inside a Disney theme park has a certain capacity, or a maximum number of guests that attraction can handle in a given operating day. For example, a ride-through attraction like the Haunted Mansion may be able to carry 2,000 guests per operating hour. During a 12-hour operating day, 24,000 guests can experience this attraction. Similarly, a live theatrical show with a theatre capacity of 3,000 guests that has five shows during the day has a capacity of 15,000 guests. When Fastpass is installed on the attraction, a certain number of those seats (in the theatre, on the ride vehicles, etc.) are set aside. The remainder are made available on a "stand-by" basis to other park guests.

Walter Elias "Walt" Disney (December 5, 1901 – December 15, 1966) was an American film producer, director, screenwriter, voice actor, animator, entrepreneur, entertainer, international icon, and philanthropist, well known for his influence in the field of entertainment during the 20th century. Along with his brother Roy O. Disney, he was co-founder of Walt Disney Productions, which later became one of the best-known motion picture producers in the world. The corporation is now known as The Walt Disney Company and had an annual revenue of approximately US$36 billion in the 2010 financial year.

Disney is particularly noted as a film producer and a popular showman, as well as an innovator in animation and theme park design. He and his staff created some of the world's most well-known fictional characters including Mickey Mouse, for whom Disney himself provided the original voice. During his lifetime he received four honorary Academy Awards and won 22 Academy Awards from a total of 59 nominations, including a record four in one year, giving him more awards and nominations than any other individual in history. Disney also won seven Emmy Awards and gave his name to the Disneyland and Walt Disney World Resort theme parks in the U.S., as well as the international resorts Tokyo Disney Resort, Disneyland Paris, and Hong Kong Disneyland.
