Archie,
That is probably a more difficult question to answer than it first appears. Certainly once the overall cost and bond issue/loan is set, the one thing the course sees that it can control is the maintenance budget. That said, interest rates (both original and refinance) might vary what they pay annually for the original construction.
Irrigation now varies from letting a double or triple row of fw heads over spray the rough, to separate rough and fw sprinklers, complete control, and even part to part heads (which sort of limit redesign of grassing lines, now that I think about it) In other words, as irrigation gets more complex, it might skew the cost of the original construction higher, with the goal of reducing or making irrigation more precise. There are other factors, too such as picking maintenance intense but better playing turf, etc.
So, in general, I tend to think today's more complex construction raises the cost of wide fairways way more than it did even ten years ago, even if maintenance is probably the ongoing single biggest factor.
Mac,
I was surprised when that golfer made that quite pithy comment, but it seems to be true. Most golfers seem to be used to being led like sheep! A double fw hole a few times a round as a novelty seems to be the ticket according to the masses. A triple or more would be a real eye catcher, but misunderstood by most.
As to the "ideal" hole that won the Lido prize, we really will never know if all those options really worked, will we? As I looked at it, many did not seem to. Also, as noted, almost any golfer will assess his options (or not, at least the dumb ones.....) and if there are twenty, he still probably narrows it down to his best two, three tops, no? So why design the others? Yes, there are different levels of golfers, but in reality, multiple tees took over in place of multiple fairways at much lower cost to try to bring the two main options into play.
Lastly, there is the school of thought that the subtle choices may be more fun and intriguing. As someone mentioned, choosing how to use a slope is fun. Picking one side of the fw over another, a high or low, left or right lay up, regular or power tee shot are all decisions to be made. Most multi fw holes are really hit it harder or layup and not as multi layered as you can make with one slightly wider than normal accuracy requires fairway.
