My first visit to MK was Disneyland. My parents gave to me for my 10th birthday, a week travel tour on a California trip hosted bya local TV clebrity - Rex Trailer. We did all the S. Cali attractions of the time - Knotts, Universal, Hollywood Bowl, San Diego Zoo, SeaWorld, Movie WaxLand, and 2 days at Disneyland! That was 1971.
First visit to WDW was in 1975, 3 days at the end of a 2 week trip to Florida. I was 14. I spent every possible minute in the MK. Wow, it was great! We stayed at the Contemporary Resort. I made a doubloon at the Pirates store on a machine where you stamp the backside. I stamped my name and the date...2 23 75. It has a hole in to use as a key chain ring. I've used it ever since, 33 years and still going. It's my daily reminder.
My next visit was in Jan 1983. I took my girlfriend for a week during our senior college break. It was her first time to Disney. She is now my wife and our boys are 11, 13, 18. Yes, they've been to WDW a few times. And DL too!
Did I mention we snuck in a day at Tokyo Disneyland? That's another story.
