Please, no wikipedia-type responses. I'd like first-hand recommendations.

I'm looking for a neat place to have a family vacation, possibly reunion. I'd like to find a place with cabins on a lake with good fishing and swimming possibilities. I don't want "Resort & Spa" suggestions; I'm looking for simple, clean cabins that have their own kitchens - to keep expenses down. In the mountains is a plus, as are additional amenities like a lodge that would allow everyone to gather at once.

I would be interested in places that could accomodate a group of 25 people, or possibly a group of 65 people. I'd like to stay in the eastern Tennessee, northern Georgia, North Carolina, or South Carolina areas, but if you know of a place not too far away from those, feel free to suggest it. Thanks!
