Jay,
Since you haven't gotten any bites...
We were invited to see the site and make a pitch. The site was REALLY tough. Beautiful - but tough. There was a (higher) section of the property which, it seemed, could accommodate some very good holes. (my recollection is, this area overlooked a power plant or something...) The area near the resort possessed tough topography, existing roads/elements, shorter dimensions - which certainly required creativity, and undoubtedly caused difficulty with the routing and connected the holes. If this wasn't enough, there was plenty of rock and rocky soil...
Again, my recollection is; we were able to route 18 holes but there were some long distances between holes. And, I seem to remember our solution was "creative" - but I can't remember the details - sorry.
Honestly, I haven't seen the course that was built.
Your architect friend was right - designing and building that course couldn't have been a cake-walk.
