First trip was around 1980 so I was 10 or so. If I remember correctly, we drove down in a camper with another family who's father worked with my step dad. His son was around the same age and an absolute a-hole. Their whole family were pricks actually. The highpoint of my trip was being in the over the cab bunk and looking down at the adults and accidentally losing my gum in the dad's hair. #Score. We drove down making stops in Washington, DC (I was accidentally left at the Jefferson Memorial while the rest of the family drove 40 minutes down the road without me), Atlanta, GA (this was during the span where there was that serial killer killing kids) at a campground where the adults were in the camper and the kids in tents. Turns out the pond right next to the camp ground was filled with gators and we came out to the remains of ducks scattered around our tents. NC, and finally at Disney. We stayed at a camp ground off-site if I remember correctly. I remember Pinocchio being a jerk, and kicked over my mom's soda. BTMRC was under construction and I remember a pic of me and my brothers at the time in front of the castle. Did most of the classics if I recall. Drove home and dropped the other family off at their house to which they found the guy who they'd had sit their house had a week long party in it. Drunks passed out all over the lawn, interior trashed.
2nd trip went down with my first ex and our daughter (toddler) and my ex's brother. Nightmarish. I don't remember much beyond constant fighting and her biting people's heads of left and right.
My trips have been much better since then, lol.
