Nope, the costs are only for those entering the tournaments. We'd love to have people there to come watch, and join in the afterparties. :]
Matt: sorry to hear you can't make it; have fun on the cruise though! If you're not busy this weekend and don't mind staying up all night for the afterparty (it'll most likely go until 9am), you can probably join in on a carpool with me and a friend if you could put $10 towards gas. Only possible problem on this side would be that my friend who'd be driving is not 100% sure he can go at this point.
