If you go to Wild Dunes, you will likely enjoy both courses. The Links is certainly the stronger of the two. The final two holes at the Links get all of the publicity, but there is a bunch of other good stuff to see out there. I particularly like number ten, which many on this board either like or despise. The Harbor course is fun, but the course feels a little repetitive after a few holes. I have family in the Charleston area and have played Wild Dunes many times over the years. And yes, there are more condos than ever. Most are not intrusive except that awful monstrosity behind 18 green.
You will hear many allude to how great the Links course used to be. That is not to say it is not a very good course still. However, before Hurrican Hugo and the condo development, the Links course was a beauty. There were many more trees and the property just felt more rugged.
Ron Whitten probably put it best in a recent Golf Digest article on whether Fazio is good for the game:
"But golf can be just as much fun, and certainly far more challenging, when played in more Spartan conditions, with a pullcart on dry, patchy fairways where one might have to improvise some shots. Tom Fazio used to design such courses, like Wild Dunes, his first 100 Greatest layout. It's a shame we don't recognize that course on the 100 Greatest anymore, and a shame that it's no longer his standard."
As for other options, the collection of courses at Kiawah is about as good as it gets.
On my last trek down to the Masters, my dad and I spent several days in Hilton Head before heading to Augusta. Although, if you are interested in playing Harbour Town, it shuts down to prepare for the Heritage on that Monday of the first Masters practice round. Playing it those last days before it closes down is quite a treat though.
