This was to be built on civil war battle fields, right?
This was a big reason why this didn't fly.
I am rooting for the American Heartland to be a success.
Disney's America was going to be built *near* civil war battlefields. The project site is now conventional suburban tract development. The neighbors didn't want the traffic. Any opposition to Disney's America other than that was pretextual.
Regarding the weather in Oklahoma, it is not that different from successful year-round parks in Paris, Osaka, Tokyo, and Beijing--all of which regularly operate in snow. (One of my favorite theme park experiences was riding Jaws at Universal Studios Japan while it was snowing. Most of my friends were eager to be in Wizarding World of Harry Potter in the snow. But Jaws was where it's at!)
The weather would not prevent a great park from getting 5 million visitors if it had the right population base...
The middle of Oklahoma does not even remotely have the population to support those numbers.
5 million annual attendance is about the same as that of Disneyland Paris, a park next to a city of 13 million, and Disneyland Paris has year-round operation despite the winters.
SeaWorld Orlando and Busch Gardens Tampa both have year round operations and get about 4 million guests per year.
A $2 billion investment in that market will create a regional attraction, not a national one. If their pro forma requires 5 million annual attendance, they are going to have a rough go at it. If they can do well at 2 million guests a year, that is probably achievable for that market. But that is a park similar in scope to Six Flags Great Adventure in New Jersey or Six Flags Great America near Chicago.
