Helen georgia is exactly where you want to go.
Do not go to Helen...it really is a tourist trap and it only takes 1/2 hour to see all the good stuff.I would recommend going to Northern GA. Ammicalola Falls is beautiful and has tons of trails.Blue Ridge is also a nice place with tons of cabins.Big Canoe is also a really neat place with lots to do and really nice cabins.If you are looking for snow, you will have to keep going North to North Carolina.
Try Franklin, North Carolina. This place is great, I ve stayed here several times- http://www.franklin-chamber.com/wayahcre��
Western NC, east Tenn and north GA mountains are full of rentals cabins. You better start looking soon because reservations fill fast for the holidays.
Unicoi.It is near Helen,but not a tourist trap. You will also be near the Appalachian trail.
Try Cloudland Canyon State Park in northwest GA, it is near Lookout Mountain.
