It has a hotel with fine dining restaurant, rental cabins, campground, indoor swimming pool, extensive stables and pasture land, tours, two museums, numerous historical building open for visiting, tennis courts, and a lot more. You can rent one of the old officer quarter homes or one of the smaller buildings that were converted to residential use, or even a large building that will sleep 60 people in multiple bedrooms and having 14 bathrooms!
