As far as I know, the only gold crown resort in the Outer Banks is the Outer Banks Beach Club II, and I think you'll have a hard time exchanging into there, esp. during peak time. You might want to look into renting a house, which is what we do each year. We prefer to rent a home, this way we are only a few blocks from the beach, but we have a private pool and hot tub. There are several realtors to choose from. The home we have rented for the last three years (as well as next year) costs us $2,300 for a five bedroom, three bath a few blocks from the beach and it is gorgeous!
There is a lot do do on the Outer Banks. Some examples are: tour lighthouses, pier fishing, beach fishing, sound fishing, deep sea fishing, crabbing (this is so much fun), water rentals such as jet skiing, boat rentals, kiteboarding, parasailing, seeing the wild horses, beach (great for boogie boarding), sea shell hunting, miniature golf, golf, relaxing, and much, much more.
You will love the Outer Banks. It is such a nice pristine place, so unlike Myrtle Beach. It has lots to do, but is so laid back and relaxing - the perfect vacation destination!
