Ah, you youngster. The early days of Disneyland issued a book of tickets for the rides. The price of admission included this book. The tickets ranged from A, B, C, D, and E. E being the most coveted. They got you onto the really good rides. It got you on the Teacups or the likes. For years the expression E-Ticket meant first class, the best. Still does. Now the Disney parks just have a flat rate for admission and get on a ride when you can. Ah, the days of the E-Ticket.
