In 1980, $36 ($105 in today’s money) would buy you a night in a hotel, admission to Disneyland, tickets to 11 Disneyland rides, and transportation between Amtrak’s Fullerton station and the hotel and between the hotel and Disneyland. Even after adjusting for inflation, that amount wouldn’t get an adult into Disneyland today (though today the admission includes unlimited rides).
This brochure also has three-day and five-day tours, the latter of which includes visits to Knott’s Berry Farm as well as Disneyland. The brochure also mentions Universal Studios and other theme parks. Apparently, the brochure title, “Disneyland & Southern California,” means “Disneyland & Other Theme Parks.”
