I was at WHC, but spent most of my time helping to run the art show. There's another convention (CONduit 18), this one covering science fiction, fantasy, and horror, held on Memorial Day Weekend (May 23-25) at the Radisson (same hotel as WHC2008). If you're a writer, it's a great place to be as there are always a variety of workshops, panels and so on which can help you improve. If you just enjoy the genre, there are plenty of activities, panels, and presentations to attend.
