Kings Island is a very well maintained and run park now to be sure but I definitely miss when the place was more about theme and diverse attractions like the Wild Animal Safari. It felt more in line with Busch Gardens Williamsburg in some ways, whereas now it is more like Cedar Point. That's not to say one is inherently better than the other, just different tastes I suppose.
Glad to hear you had an enjoyable time there, and it sounds like you managed to fill over two days without running out of stuff to do (which I thought sounded like major overkill). I can't wait to hear what you thought about Cedar Point.
Lastly, just for fun, here's how I'd rank Kings Island's coasters (best to worst): Banshee, Diamondback, Beast, Firehawk, Flight of Fear, Racer, Backlot Stunt Coaster, Bat, Vortex, Woodstock Express, Adventure Express, Flying ACE Aerial Chase, Invertigo
Our coaster rankings are similar, just a few changes: Banshee, Beast, Diamondback, Firehawk, Backlot Stunt Coaster, Flight of Fear, Racer, Bat, Vortex, Adventure Express, Invertigo, Woodstock Express, and Flying ACE Aerial Chase.
Regardless of the order, that list is a really nice collection of quality rides.
