And I can vouch for Jeff when it comes to Worlds of Fun... the park definitely needs something since right now it is more like Shanties of Fun. Ugh.
As for closing American Idol Experience, thank goodness! That show hasn't been relevant in some time. I am a little dubious that anything will actually be done with the building. I know there are some other buildings such as the Drew Carey thing and whatever is next to Pixar Place that seem to be worthless, but apparently it's used for special events or storage.
Hopefully those are just placeholders for when they have enough vacancies to close off an entire section of the park for a vast revamp.
But like James said, I appreciate the effort to think outside the box, especially for Cedar Fair.
