We have camped on this site before. It is definitely long enough as we camped with a 28 ft 5th wheel. You will have privacy, however, the site is a bit narrow. We ended up having to set up screen house near the back end of the site just to the rear of the rv. The site backs up to a paved road (after a short walk through the woods) so there will be no campers on the back side of you. You will be on the back loop so the walk to the beach is a bit long but certainly doable. Love that campground. Hope you have a great trip.
