We stayed at BWV for halloween 2yrs ago. We went to the bw party. It was great. They had a dj, a costume parade for the kids, gave out candy all along the bw, you got to decorate your own witch and bat cookies, and there was a pumpkin carving contest that you could vote in. If I remember right it lasted 2-3 hours. It was free and there seemed to be a lot of locals there. It was a great way to spend halloween if you weren't going to the parks.
