Doing some quick math, if the upkeep is $5M a year, and you do camp 50 weeks a year, it could work out. With 80 homes you could probably easily house 400 people per camp, each camp is 1/2 a week, so you'd need about $110 per person towards upkeep. Probably $100 for food, $100 for staff. It look like they charge about $700 for 3 days, so that still leaves almost $400 per person for all the stuff I didn't think of.

The question is whether you could find 400 people 100 times a year.

Transportation would be an issue too. Assuming you were targeting individuals across the nation, they would likely be flying into the nearest regional airfield. You would likely have to bus 400 people within the same 4 hour window one or twice a week, so you would have to maintain or rent a fleet of 10 buses and drivers.

Unless you were in a very big city, I don't think the taxi/uber infrastructure could handle a surge of 400 long trips within that kind of window.

Uber wouldn't be allowed, anyway. It depends on the driver having an ongoing connection. They use the GPS trail for fare calculation.

Not to be funny, but considering its location and surrounding, I don't think it's attractive as recreational facility. Maybe obesity camp, internet addiction detox camp, or perhaps isolationist religious cults.

Anyone looking to truly disconnect from the world. Being able to tell the office "I literally will not be reachable" and have it be true is wonderful.

Looks like the goal of the camp is to get away from "life"
