They are already in financial disaster, do you know how much they are in debt? Alot. They weren't very smart with their money.
Yes, they are in debt, financial disaster? No. If they were in financial disaster, they'd be selling off all but a few parks or the parks would be going into foreclosure. They may have taken on too much when they acquired Paramount Parks, but it was either all or none. They saw the potential for growth both in portfolio and in finances (yes even some loss helps gain).
Only one at Kings Island? Diamondback (1), Banshee (2). You have seemed to miss the point that CP is part of the flagship, of course they're going to have major record breakers. Since Cedar Fair has acquired Paramount Parks, Cedar Point has gotten how many record breakers? 2006 Skyhawk (world's largest swinging thrill ride), 2007 Maverick and in 2013 Gatekeeper. So they're only 1 record breaker ahead of Kings Island.
But remember just because a ride is a record breaker, doesn't mean that it's the best for a park. Those that push the limit also push the strain on operations. Maverick, how late did it open compared to it's scheduled opening day?
I agree with you, there can be more added to the park, but to imply that they really don't care to add much to Kings Island isn't correct. Be thankful that they've done so much around the park when a major ride isn't added.
How is Diamondback a world record breaker? And every ride, no matter what the size will have some problems of it's own, large or small. I guess I'm just ranting cause I want KI to be as good as possible.
