I am sure that money was a big factor in determining the height and length for MF. Cedar Fair is a public company, and like all companies, is expected to turn a profit. Money spent on new rides subtracts from the bottom line. Would a 400 foot coaster draw significantly more people to the park then MF? Certainly not enough to justify the extra cost. What do you think is a better strategy for CP – to build a 400 foot coaster and then not build anything record breaking for 10 years, or build a 300 foot coaster and then in 5 years build another record breaking coaster? The two coaster strategy will draw more people because you can hype each ride. And I don’t think CP cares too much about some coaster in Japan. Not too many people living in the U.S. are going to suddenly stop going to CP because there is a bigger coaster in Japan.
And to say that MF is paid for after 50 days of operation is silly. It cost a lot of money to pay all of those employees, buy the food, maintain the rides, etc. Plus, for the ride to pay for itself, you have to look at the difference between what CP would make without MF versus what they are making with it.
