This special passport was part of the "Splash for Cash" promotion for the grand opening of Splash Mountain at Disneyland. Somewhere on this blog I posted the second version of this ticket that included an additional day due to the delay of the grand opening. I'd link that old post, but I can't find it, I need to do some better indexing of these posts!
This offer open only to McDonald's employees. "would you like fries with that?"
