Who in the world in their right mind invests the multi millions in a high end golf destination, if not to know or have an almost airtight lock on the demographics of their end user?
Those demographics vis-a-vis the quality of the golfer and their affluence obviously changes with the location, the overall theme of the project, and the philosophies of the developer.
Keiser, Kohler, Pascucci, Bakst, Youngscap, O'Neil are golfer-sportsperson oriented, but knew full well that their target audience wasn't going to be coming to lie on a beach in the lap of luxuary. Yes, they also provide facilities and on-site luxury since in most cases there isn't anything to do after the golf rounds there. But, they started with a golf centric notion and hired archies to bring that in.
Cap Cana is a totally different animal, from what I could glean on their unfinished web site. It is selling a lifestyle where golf is a leisure time, status, recreation, with sales sizzle for all the other stuff. So, they hired the archie with the big name, and experience in design for such, who will sell the best of the overall product. It isn't golf centric, IMO.
