I found this site about club33, im still looking at the pictures. There's alot of info on here, but it has a history page so you could check that out. I've always wanted to go to Club33! I've never even been to Disneyland, so I guess I should have that be my first goal lol.
Ok- that was on the site (posted below) or is it wrong...?
When the park was opened, there was a select number of lessee's who were the major sponsors of Disneyland. As the years progressed, some sponsors left, other were added.
Here is a list of the Disneyland lessees from 1966-67. Count them and see what you come up with!
