Michael:
Bandon Dunes Resort pioneered the ten-hole opening, or, at least, the formal ten-hole opening where you pay to play a course that's only half finished. It has been VERY successful there in generating early buzz for the new courses, not to mention defraying some of the costs of grow-in maintenance; so it's not surprising they would do the same at Cabot Links, under Mr. Keiser's influence.
It is not as clear whether it will work. What makes it work at Bandon is hundreds of golfers booked on the other courses chomping at the bit to get a peek at the latest course; and they open without hiring much in the way of additional staff. Opening a new course is a much different equation. However, part of the premise of Cabot Links is attracting drive-by visitors from the summer tourist season on the Cabot Trail, so maybe it will work there.
