My family goes to OBX practically every summer for the last 6 years. It's a blast as there isn't much to do. you get a chance to truly relax and enjoy the time away. Just a heads up, a lot of places will be rented already so you may not have a great selection for this summer. It all depends on what type of house you are looking for and how close/far from the beach you would like to be. We rent the larger 8-10 bedroom houses and try to stay by the beach.
Have a great time! I'll be down there the week of July 7th!!
