The 5 Day World Hopper pass I bought for my Oct. 94 visit has my photo on it. It's black and white, one inch square and is the same quality as one might have expected to see in a newspaper. It is obviously me. I believe Disney did this to try to reduce the number of people who sold their unused days to other people.
Back then the pass was 7 3/4 by 2 1/2 inches and was punched in a machine as you entered the gate, indicating the date and time of entry. They didn't use the photo passes for very long. I didn't have one during my Feb 93 visit, and they were gone by the time I went down in Feb 98 (replaced with the current magnetic stripe version).
During my Jan 2000 solo visit I did experience one unexpected bonus to still having one day left on my 94 pass. They were still accepting the pass at the turnstile even though the magnetic ones were the norm (don't know why Maryann F had a problem in 97).
They had recently introduced the Fast Pass system and because the system was so new, every kiosk had a cast member explaining how the process worked. As my pass wasn't designed for the system, I would show it to the cast member who would then manually issue me a Fast Pass.
Since the computer wasn't reading my pass, it had no way to keep track of how many Fast Pass tickets I was getting...no restricting me to just one FP at a time. I could keep going back again and again.
Oh yeah, one other thing. The 1994 5 Day World Hopper pass was back in the day when the 5 days were for addmission to just the parks. They also included from the first day you used it, 7 consecutive days of UNLIMITED use of Pleasure Island, Typhooon Lagoon, River Country and Discovery Island. The cost for all this fun? With my Magic Kingdom Club discount.. $170.51 plus tax. Those were the days. I still have the pass as a memento.
