FYI...
This is info for Mt. Vernon, KY. This is about as close as it gets from the north. London & Corbin have more motels, but I haven't researched them yet. I'll try to add them later...
Lodging Info

Kastel Inn looks like the best motel bet at $55/night on weekends; $42 if we have a group of 10 or more rooms
Lake Linville Camp Ground is sending me a brocure, but the info is $10 for tent and $16 for an RV; he'll figure a group rate for us when we know about how many will be there.
