A number of high-end resorts--e.g., Bandon, Pinehurst, Sand Valley--have built par-3 courses that have been well received and that appear (anecdotally at least) to be quite busy. Are they generally more or less profitable than the full 18-hole courses? On the one hand, of course, the greens fees are lower--but they might have more rounds/day, and in any event the expense side is almost certainly lower too. Or are there so many variables that this will be context-specific and one can't draw any general conclusions?
