I stayed at the Hiawasse Inn in Hiawasse GA during a recent section hike and was impressed with the hiker services. Its the closest commercial establishment to Dicks Creek Gap and looks to be an easy hitch. It is about a mile closer than Molls motel (which seems to be in only semi operation). It is set back off the road and is almost hidden. There is only one sign, look for a Marathon Gas Station and drive out back. I dont have their info right at hand but they claim to be in both of this years guide books.
The owners of the Inn offer rooms or tent space, laundry and shuttles (50 cents a mile round trip from the INN). Two free shuttles in the AM to Unicoi or Dicks Creek Gap. They will shuttle to Springer (the gap 9/10 north of the summit) all the way to Fontanna. They also offer limited slackpacking. They also do afternoon pickups at Unicoi and Dicks creek.
They have been in operation for a year and a half and had over 700 thru hikers stop by. The owners really look to be pursuing the hiking community and try to help out. The owners take some pride in their place and seem to be pretty flexible, but I did sense that if someone has an atitude they may not be welcome.
One caveat is that they do not allow illegal drugs on the premises and the local police stop by on occasion with their drug dog to scan the rooms.
