I was at Disney World in high school (yawn, lol, but we went mostly for my little sister and my folks let me run free all day) and then took our girls when they were young. Still feel guilty we never got back since the youngest really didn't sustain many memories at all, poor thing. She was a week short of turning 3 and she was free, haha, and she had a good time but mostly we don't reminisce around her.
At that time, some 20+ years ago, we actually enjoyed all things Sea World much more and our oldest really liked the safari thing at Disney World - she got to see live Cheetahs - a huge deal for her.
A couple of nights in Nashville and seeing Riders in the Sky at the Ryman Auditorium was the highlight for me and there was a huge civil war/State museum nearby downtown and the oldest was also thrilled it had mummies (no idea why they were there other than some guy from Tennessee probably raided a tomb, but they were a feature).
