Was at BG over the weekend. When we left mid afternoon they were parking across the street which always is a sign of big crowds. Last time we were there (last season), DK was a walk on so it seems to have lost popularity. As I recall, before they build that, there was a very entertaining Wild Mouse type coaster there.
It would be nice if there were more indoor areas. As the weather was brutal on Sunday, the Festhaus was pretty much the only place to get a break from the heat (they were not showing Celtic Frye which was a surprise for me.
