John, you list the first benefit as "provide a superior product" yet borrow from the McDonald's brand in your thread title. There is a HUGE mass market out there that either doesn't want or doesn't care about superiority, whether it's burgers or golf courses. They simply want to satisfy a need by buying a known commodity of acceptable quality at an affordable price, preferably with a limited time commitment. I fear this is where your plan breaks down. The mass golf market has no need of golf course architecture, at least not as we discuss it. They certainly won't pay for it, or favor it over a course that's closer and cheaper, at least not on a repeat basis. Given them true greens, grass on the tees and carts and they're good to go.
Absent land cost, the economics are otherwise compelling. 30,000 rounds a year at $50 minus operating costs of $500,000 yields $1,000,000 cash flow repesenting a 20% yield on a $5,000,000 investment. It's a lot easier to find 1.0 acre for a McDonald's than it is 125 acres for a golf course. That, and a McDonald's can simply locate at an interstate exchange to capture transientand local traffic. Not sure many people will see a golf course and pull over.
As always your theory is well reasoned and I appreciate the time you've taken to lay it out. Forgive me for being so pessimistic.
