Tickets for Platinum ticket holders of this year's Eyecon will go on sale August 22nd, and everyone else can purchase tickets starting August 29th. They're limited to 100 cabins, so tickets seem to be fairly limited.
Prices start at $1223 and go all the way up to 2293 per person based on double occupancy(depending on which type of cabin you choose.) Looks like they will have a payment plan, with the initial installment being $200.
All the info is here.
ETA: I also noticed this will be replacing the regular Eyecon convention for 2009. So there will not be another convention next April.
