Rick,
We used to do North Carolina on my teacher break (3rd week February) and it was simply not worth it. You might get lucky and score good weather, but the two Pittsburgh guys in a Pinehurst tavern (not Ross' place) drowning their sorrows in Irish Car Bombs. Why? Their round on #2 had been snowed out. We went to South Carolina that day, from Pinehurst, to find an open course.
You have to go all in, and get below the frost line. I have zero skin in the resort game, so I'll leave it at that. Best of luck. Can't wait to hear of your adventure.
