Back when they still used lettered tickets, we would stand near the exit around closing time and ask people for their leftover tickets. Folks from out of town had no use for them, and we accumulated huge stacks of tickets. We would then get in for the general admission price of $1.50 and ride all day long.
I went to college near disneyland. My biology lab partner, Trish, worked on the Matterhorn ride. I used to pay general admission, go the the Bobsled ride, and get Trish to take tickets. She once gave me over a hundred E coupons.
I wonder what ever happened to her....great lady.
