From Disneyland's opening day until 1982, the price of the attractions was in addition to the price of park admission.[59] Guests paid a small admission fee to get into the park, but admission to most of the rides and attractions required guests to purchase tickets, either individually or in a book, that consisted of several coupons, initially labeled "A" through "C". "A" coupons allowed admission to the smaller rides and attractions such as the vehicles on Main Street, whereas "C" coupons were used for the most common attractions like the Peter Pan ride, or the Tea Cups. As more thrilling rides were introduced, such as the Monorail or the Matterhorn bobsled, "D" and then eventually "E" coupons were introduced. Coupons could be combined to equal the equivalent of another ticket (e.g., two "A" tickets equal one "B" ticket). From the thrill ride experience at Disneyland, the colloquial expression "an E ticket ride" is used to describe any exceptionally thrilling experience.
