I've never been to Kentucky Kingdom, but I've found the story of the park really interesting to follow. I know this will be a simplistic way of looking at it, but Ed Hart built the park up, Six Flags ran it down, and now Ed Hart's building it back up again. It might not necessarily be the case that Ed Hart's formula could work for a theme park in any location, but he does seem to know his audience very well and have a good sense of what will and won't work. It feels like anyone who's interested in studying theme park management should take a look at Kentucky Kingdom.
