Nickelodeon Studios for the simple fact that the tour was the main reason I went to Orlando but never actually went on it.
I'll tell the quick story as to why. I was a huge Nick fan in the 90s (who wasn't?) and after seeing "Kenan and Kel was recorded in front of a live studio audience at Nickelodeon Studios in Orlando at Universal Studios Florida" I wanted to go there and see a show live. My aunt did the research and found out that Disney was nearby. After being pushed back a few years thanks to me having to attend summer school :doh: we finally were able to take our first vacation in 2001. I planned on visiting Nick and then spending the rest of the trip in Disney because what kid doesn't want to go to Disney? I had no idea that Nick was located inside a theme park. I ended up going on every ride at Universal and Islands of Adventure that I could (I was only 9 at the time) and never once stepping foot inside Nick because I was too excited by the rest of the rides in the park. When we finally got to Disney, I was bored.
In all the years following, I just never bothered with going into Nickelodeon anymore and I sort of regret that. But hey, I had fun taking pictures of the "slime" fountain, which did annoy me when I saw it in person and I could tell it was just colored water.
