I think that the only true section that needs to be completely redone is Action Zone. This area, in my opinion, was designed to be a thrill ride area, but doesn't practically the entire park revolve around the thrill rides? I just hope they find a way to tie in Congo Falls into Top Gun.
Other than that, i hope that they just revamp the scenery in all of the other areas. Adding Foliage and maintaing the park is key to this restoration. I hope CF will review the history of the King's Island and take this into account when, hopefully, restoring the theming. What CF must remember is that the guests to King's Island know it as the park that they visited as children (which for me wasn't that long ago but I do believe it was better then than it is now) and that if they can restore the park to its prior grandeur and fill in the park with high quality rides they can make KI a great park that people will frequent because of its family friendly atmosphere AND its innovative, thrilling rides
