You are prolly correct. What I would expect is phase one being made and then a "wait and see" approach for phase two.If I'm being real. No way this park actually ever happens. Yes, they are breaking ground this year but only on an RV park and campground. If it does happen, it will not be on the scale or size of that concept art, because they have no money to do so, I honestly doubt 2 billion is enough, and for reference, Epic Universe is costing north of 6 billion dollars, and will probably be the most expensive theme park ever built.
The size and scale (and cost) of phase two is entirely based on the success of phase one??. If it "is" popular? It "should" continue to grow and grow over time based on that customer demand. If they can successfully tug on our patriotic "red white and blue" heartstrings and grow from "that" love? I think it's possibly a strong recipe for success. If phase one "really" creates demand and it performs well? Will phase two bring even more investor support? The overall "theme" of this park certainly has an inherent "built-in" audience. (Unless they get "political" or go "activist"...which would destroy and wipe-out the entire park attraction draw immediately)
On the cost?...hmmm...I wonder what the land cost, local tax incentives, and construction costs of Oklahoma are compared to Orlando? I would have to suspect that the state will bend over backwards to help this theme park get built in their state. I would guess there is ENORMOUS local and state government support for this???
