We rented a large house with 7 bedrooms and 6 baths from Joe Lamb and Associates. A quick google will provide you with several agencies that rent houses. As Mister2 indicated it is a popular spot for mulitple family gatherings. We had my folks 50th wedding anniversary in the OB and everyone had a great time.
Beach, water sports, fishing and golfing are the most popular activities.
