Ticket book

Admission coupons bundled in what are commonly referred to as ticket books (officially coupon books) were the primary type of admission permitting the bearer into attractions at Disneyland and the Magic Kingdom from 1955 to 1982, and at Tokyo Disneyland from 1983 to 2001. Park attractions were originally not included with the price of admission to the park, requiring guests to either pay an entry fee at an attraction's entrance or buy a ticket book containing multiple tickets that could be redeemed for entry onto an attraction.

History
When originally introduced at Disneyland in October 1955, the books contained three "A" coupons, two "B" coupons, and three "C" coupons. The letter grade determined an attraction's level of excitement. "A" coupons granted entry into tamer, less-intense attractions, while "C" coupon represented more thrilling, more popular experiences. As such, the monetary value of a "C" coupon was worth more than that of an "A" coupon.

By 1956, Disneyland added a "D" coupon as more attractions were added, with popular attractions such as the Jungle Cruise being upgraded from "C" to "D".

Disneyland's first major expansion in 1959 saw the opening of major attractions such as the Matterhorn Bobsleds, Submarine Voyage, and Disneyland-ALWEG Monorail System. All three new attractions required the newly-introduced "E" coupon (more famously known as the "E" ticket). Since then, the term "E" ticket continues to be used in theme park terminology to refer to attractions that are a park's most popular, most expensive, and/or technologically advanced, even long after the discontinuation of ticket books.

On October 1, 1971, Walt Disney World opened, with its flagship Magic Kingdom park utilizing the same ticket book system in place at Disneyland.

Competing parks, such as Knott's Berry Farm, would also go on implement ticket books. By the late 1970s, however, ticket books were falling out of favor, as parks like Six Flags Magic Mountain introduced unlimited use tickets, granting admission to the park and unlimited use of its attractions all for one price. The nearby Disneyland would introduce a similar unlimited use ticket (the "Passport") on June 20, 1981, alongside the ticket books. The popularity of the Passport led to the complete discontinuation of ticket books at both Disneyland and Walt Disney World in June 1982, only a few months prior to the opening of EPCOT Center.

While the stateside parks abandoned their ticket book system in 1982, Tokyo Disneyland would open on April 15, 1983, with the ticket book system. Ticket books would be utilized there until March 31, 2001, as the property was expanding into the larger Tokyo Disney Resort.
