My first (and only, to date) visit was in July 1987. I was 5 years old and it was the first time I ever remember going on a "big" vacation. My parents took turns driving and we drove straight through from Missouri; my brother and I took turns sitting in the seat or laying on the make pallet my mom had made for us by pulling out the middle seat of our '85 Plymouth Voyager.
I don't remember a whole lot of the trip, since I was so young, but I remember falling in love with the Swiss Family Robinson treehouse, PoTC, and Snow White's Scary Adventures. I also remember having a great time playing on Tom Sawyer Island.
The one memory that stands out most for me, though, is being in front of Cinderella Castle to meet Mickey, Goofy, Donald, and Pluto. I got my picture taken with Goofy, Donald, and Pluto but just as i was about to make it to Mickey, they whisked him away and said he needed a break. I bawled my eyes out! LOL
