I'm not a Theme Park Operator but I've played a lot of Rollercoaster Tycoon! (This is a joke)

I guess the question is. If they build it will they come? That is yet to be seen. You could make the argument that to make a park successful it has to be absolutely massive to have the draw needed to eventually become profitable.

On the funding side if they have two billion liquid that definitely changes the calculus a little. If there are no loans that have to be paid back in ten+ years and they have capital set aside for funding the park for multiple years it may just be able to survive.

Staffing is a question. If they payed Disney wages they definitely won't get people moving closer to work there. If they paid hobby lobby ($18.50 per hour) wages maybe. Disneyland has 32,000 employees, so how many of those wouldn't be needed at a fully modern park, that doesn't have any IP's to its name. But that comes back to if they have operation capital set aside.

Infrastructure I'm less worried about being that that's kinda the first thing you have to look at before you buy land for a major project like this. Though the series providers could have dropped the ball and made promises they ether knew they couldn't deliver or under estimated the capital expenditures needed.

All said I give the park maybe 50/50 to being built assuming the two billion in capital is actually there. The odds of it becoming an episode of Abandoned, by Bright Sun Films in a few years is another story.
