Been going to the OBX in early Aug for a few years now with a lot of family. We have stayed in Duck and Corolla. Rented houses within walking distance to the beach and had pools, usually did the beach in the morning into the afternoon, back to the house for swimming and dinner. Corolla is farther north but we like it there and will be there again this summer. Weekend traffic is bad, during the week it seems to thin out a bit. If you go in October I would think the traffic to be very light and the water will be pretty cold. Not a lot of night life up by the resort your looking at, will have to drive north to Corolla or South back into Duck. It's much more commercial in Kitty Hawk, Nags Head, and Kill Devil Hills. We liked the Wright Brothers Museum in Kill Devils Hill, and the aquarium on Manteo Island. The Lost Colony of Roanoke is pretty cool too. Get some Duck Donuts for breakfast!
