Some daily fee possibilities worth considering:
Crooked Creek in Alpharetta on Hgy. 9
Windermere in Cumming, just off Ga. 400
Chestatee G.C., farther up 400 north of Cumming
Cobblestone in Acworth (NW side)
Emerald Pointe at Lake Lanier
Woodmont in Canton
All are excellent, and I have left out a number of other daily fee courses that I either haven't played or wouldn't recommend. Crooked Creek is a favorite of mine, as is Woodmont, but Cobblestone is probably the best of this bunch. It would be a bit farther of a drive, however.
As to reciprocal agreements, you might call Cherokee Town Club, or the Ansley Club's Settindown course.
Let me know if any of these are of interest, and I'll provide any further information that I can, as well as driving directions.
