Super noob here. I'm going to be attending my first PAX this year. I've seen lots of talk about pub crawls and the like, and I'm sure there will be tons of impromptu hotel parties and such, but I'm wondering what else goes down. For example, at SXSW, there is the "official twitter party" at this bar on Friday, the "official tumblr party" at that bar on Sunday, etc. Are there parties like that - planned around PAX but which are not official PAX events?
