When WDW opened in 1971, each ride required a separate ticket, which was not included in the price of admission ($3.75 at the time, which, adjusted for inflation, would be $21.66 today). Each ride was categorized as a letter from A–E depending on the level of excitement. The Carousel was A, Space Mountain was E. Disney’s more thrill-based rides are still referred to by those in the know as “E-Ticket” rides. The ticket prices ranged from 10–90 cents (50 cents–$5 today).

That means for the price of buying one adult ticket in 2014 ($99) you could get admission and 15 tickets to ride Space Mountain. Or 154 rides on Cinderella’s Carousel.
