Disneyland replaced individual ride tickets (in use since 1955) with its new passports (single admission price to the park) in 1982.
"I remember the first day we had paying guests in the park and Walt was over at the Fire Station looking out the window. And I heard him say, 'Paying guests I love you' ... and threw them a big kiss."
-Hank Dains (original Disneyland Cast Member)
