As Andy said, Atl golf depends on where you are staying and how much driving you are willing to do.
I'll add another possibility; Arrowhead Point at Richard B. Russell State Park was just listed as the #2 Best New Affordable course by Golf Digest, and it is superb. The drive from the perimeter on the north is about an hour. If you are up for a little driving early in the morning, an awesome day is Mike Young's Cateechee in Hartwell, then 20 min. down the road to Arrowhead Point. That leaves you an hour back to Atlanta when you are done.
I'm always out of town that week for Spring Break (high school) but when you know for sure where you are staying, IM me and I can make other suggestions. All this assumes, of course, that you are not going to Cuscowilla; that would always be the A+ option.
