I think I have everyone beat, so far. My first trip to
DisneyLAND was in 1966!! We had to buy the ticket books and choose which rides we would do based on the letter on the ticket. Dad would never buy us more than one book each, so we never got to ride everything until the company he worked for starting doing company night once a year. The park would close at either 6 or 7 pm to everyone except the employees of McDonnell Douglas, and then we could ride anything with NO TICKETS needed. What a blast! Needless to say, I've been a Disney fanatic forever.
My first trip to WDW was in 1985.. We went the first week in January since we didn't have any school-aged kids and the park was empty. So much fun. I think there was only MK and EP then. The biggest memory from that trip is we stayed in Kissimee (there weren't many resorts back then), and our van got broken into during the night.
