Based off some of the logic I am seeing almost every park in this country is going under because "Ultra Mega Theme Park Parent Company did not build a record breaking ride every year at Not So Mega Local Park." Simply put with out having financial record of each park this subject has little substance. Even attendance numbers that are estimated based off what you saw on a non crowded day at a park are flawed. Some of the highest revenue days at South Texas parks, FECs, and other tourist venues are days that attendance reflects low during Holy Week, however most of those attending are from Mexico and are very wealthy. The spend high dollars on many things at each place.
SFNO was wrecked by a hurricane, but yes it was likely in a struggle as it was a leased park with revenue sharing schemes that made it hard to be profitable and had capital milestones. SFAW was actually performing decently well, but in a last ditch effort to save face was put up for sell on a false hope of banking huge dollars off the sale of the land in the proxy battle. SFKK was a similar issue to what would have happened with SFNO. They did not own the park out right.
Parks are very very complicated business. A seasoned guest would often have a hard time knowing how well one if performing. Heck, even one who works at one and has for years would have a hard time guessing. Unless you have the numbers it is hard to tell.
