I think you nailed it on the head, Randy. That part about competition is right on. If they can maintain attendance, they won't build.
In mid-November, you'll understand where I get this from, but for any capital expenditure in said park chain, they do things purely on the prospect of return on investment (ROI), and not to set records or boost their egos. They are treated to a certain degree as individual business units. Amusement parks are not, after all, philanthropic organizations, even though they're about nothing but fun for us.
Valleyfair and Worlds of Fun both did about a million visitors last year, which is still very much a "regional" attraction. If either park will build a new ride, the management has to calculate how many people they need to attract to the park and what their per capita spending will be. Contrary to popular belief, each park does have its own budget to work with, and capital expenditure is granted when they can prove the ROI will pay for the new attraction in a short term.
Let me use a real life example, then we'll do a hypothetical at Valleyfair. Millennium Force cost $25 million to build, while Breakers Express cost about $15 million to build. For the new ride, they had to research to figure that they could attract a certain number of visits at a certain cost of admission. They had to figure that those people would spend a certain amount on souveniers, food, and perhaps accomodations. The interesting thing is that they have said it would take more than a year to pay this one off. The hotel was probably paid for by the end of the year. In that case they knew it would cost a certain amount per room, and after operating expenses would cost a certain amount to pay off the room. Given their 100% booked on-point hotels, they knew they could have similar success.
Now to Valleyfair. Let's say they want to build a $5 million CCI (that's the going price for a good mid-sized ride).
