Every time a new course has been built at Bandon to meet excessive demand on the previous supply of courses, folks just stay a day longer to play everything 1x or 2X, and so they build another one to meet demand, in which case folks stay an additional night, etc. So demand doesn't abate
Given the economy, it will be interesting to see if folks think enough of Old Macdonald and of the resort to stay yet another night. Until that happens, I can't imagine Mike Keiser seriously planning a fifth course. In other words, it won't happen fast.
