Our cabin is 3 miles from Amicalola State Park ... Here is my $.02
Be ready to drive to Ellijay, Dahlonega, Dawsonville, and/or Jasper for dining. Big Canoe is 10 minutes away, so you might check with some folks from there about their dining inside the development.
Dahlonega has some good choices: Corkscrew, Dantes, Yahoola Creek Grill, Crimson Moon
The dining room in the lodge is OK, but you will want to get out-and-about.
Here is something I have been meaning to check into... a day hike up to the Hike Inn (above Amicalola Lodge) and get a meal.
