Cleanliness was our biggest concern, after reading review, but it was OK. Not great, but how 16,000 rentals get cleaned in six hours, I'll never know.
The biggest issue/benefit of this property is the location. It is about a thousand feet from the Currituck Reserves, which makes for an amazing wildlife experience. However, the traffic getting in and out is insane. During the week, if it rains, the traffic on route 12 is a complete standstill. Be prepared, plan to walk or bike a lot, and schedule activities for off-hours as much as possible.
For the negatives of the congestion, our vacation was absolutely amazing. My large family had a great time, lived on the beach, dined at home a lot, and went for excursions every other day. Being so far north, there is tons of room on the beaches and local activities. It was the most relaxing vacation we have had, probably ever.
