I was 5 and it was 1981.
My parents thought it would be just like Six Flags where you bought the tickets and then walked right in. They kept telling us that we weren't going into Disney World, but would just look at it from the parking lot. The entire walk from the car, to the ticket counter, and to the boat all 3 of us kids cried that we wanted to go to Disney World and not a stupid parking lot. My mom said that people kept looking at them like they were the worst parents ever, but they still didn't tell us. My mom said that even as we were walking in, we were still crying. It wasn't until we saw the castle that we finally stopped.
