Tourists used to have to purchase “E” tickets to ride the most popular attractions, and the term is still used today.
Between 1955 to 1982, guests at Disneyland and, later, Disney World had to purchase separate tickets for each attraction they wanted to ride. By the late 1950s, the rides were broken up into five tiers — A, B, C, D, and E — based on their popularity.
“E”-ticket rides were the most coveted attractions, and although Disney got rid of the system, the term is still used to refer to the major, top-tier attractions at the parks.
Today rides like Star Wars: Rise of the Resistance and Mickey and Minnie’s Runaway Railway would be considered “E”-ticket attractions.
