Dahlonega - The Hiker Hostel - bunks, great breakfast included, laundry for a small fee, computer, nice area for hikers to hang out. Josh will pick you up at Woody Gap if you call.
Hiawasee - We stayed at the Hiawasee Inn. The owners there, upon hearing we were a family, immediately gave us their big "apartment" type room complete with a kitchen for the same hiker rate. Friendly staff. Laundry available. No computer that we could see but check with the owner. Shuttle to the trail for a small fee. Great AYCE buffet in town. Groceries.
