It's been over 20 years for me, I don't remember exactly when we visited the last time. We moved away from the Cincinnati area in 1993.
It's been about 10 months since I've been at a park though. We lived in Orlando for a little over a year and did Disney, Universal & Sea World. I worked for Disney for a little over a year in fact.
I'd be interested to visit KI to see how it compares to the Central Florida Parks, mostly in terms of operations.
