It depends on how you use the superlative "large": area taken up, money spent, time spent, importance to the future of the park, importance to the current state of the park etc...
My guess is that more time and money has been spent in SoB (at least in recent history) but The Beast is obviously much more important to the park.
And unless Frank changed his original post since the time when Terpy read it and I read it but from what I can tell, Frank wasn't just talking about next year...
As far as I can tell, Frank realized that.
But it does seems like Kings Island, under Cedar Fair, is trying to return back to the basics. More and new entertainment was added last year along with the jump and rope walk events. They even added much more garbage cans.
I don't know if anyone listens to Behind the Thrills podcast but a few weeks ago our own Don Helbig was interviewed on there and he talked about bringing street performers to the park. IMO, nothing beats a good Barbershop Quartet.
Well, maybe something "Maverick-y"
