Last years got messed up a bit like Spike said, by the rearangement at the last minute.
I do think this is important though. As I did last year. I met a ton of people there and for a while afterward there was a few times when I had an exchange that would go something like this......
"Wasn't the fest a blast?"
"Ya, sorry I missed you. We gotta make sure we meet next time"
"Uh......... dude.......... I bought you a beer"
