Scott,
The website gives good directions from AC.
However, be careful making your turn off the exit ramp on the Atlantic City Expressway, it's very dangerous, especially with heavy early morning commuter traffic.
I'll probably take the ACX to the GSP south, to exit 36 and follow the directions from there, just to avoid the hazardous, and I mean hazardous left turn, onto a road with semi blind traffic approaching around a curve and over a hill.
