Neither do I but apparently, Funpub had set a certain date and place for the 2012 JoeCon; people paid for hotel bookings, flights and attendance fees (As you do) with plenty of time in advance.
Then, a weeks or so ago, Funpub decides to change both the venue and the date and you can imagine the complete cluster-f*** that ensued; people have had to pay up to $300US on top of what they've already paid just to be able to attend, some were paying a difference of $100 just in local flights so I'd hate to be anyone International who's attending.
For interests sake, you can get a run down from Hisstank.com.
(Out of Funpub's control, I'm sure)
