We went to Williamsburg last summer, and felt that the Williamsburg Bounce Pass was the way to go. It was unlimited admission to Colonial Williamsburg, Busch Gardens, and their waterpark for 7 days. It also included parking. You can get the Bounce passes through the Williamsburg site or the Busch Gardens site. I believe they were slightly cheaper through the Busch Gardens site. It was a great time, the coasters are great there!
