If you are looking for something in the summer your best bet would probably be to rent a house for the week. Barrier Station Kitty Hawk has 3 and 4 bedrooms. They were recently bought by Gold Key of Virginia Beach and are undergoing extensive renovations which look nice. It is not a directly on the beach. You do see shoulder season inventory in RCI. There are about 5 or 6 others that exchange through RCI that have 3 bedrooms. None are particularly fancy. Most have basic outdoor pools that are heated somewhat but not enough to use during the off season. Not all have indoor pools available.
