Rick, you might consider Smokemont. You would have plenty of camping room plus you would have a greater choice of water to fish. I don't think you would need reservations especially during the week. I am going to Smokemont Wednesday for 5 days and then I'll be out there again in October for another 5-6 days.
The folks at Duke power are shutting down the power plant on Nantahala for several weeks and the Nantahala should be very wadeable and some excellent fishing. You might consider that area. You could camp at Deep Creek and fish either...........all sorts of possibilities...........tight lines
