The latest I've been hearing is that the tickets and all the hotel package info. will be released sometime in Sept.(I heard late August floating around San Diego) but I have a feeling it will all coincide with a big SW.com/hyperspace/Insider Mag blitz.
I'm guessing tix. will be avail. for order online shopsw.com Tix. for CII ran about $75.(prob. slightly higher for CIII since another day has been added this time)
There are supposed to be blocks of Hotel rooms that Lucasfilm and/or Gencon have reserved that will probably be sold as package deals and/or "special" rates.
You can book your room on an individual basis right now and I suggest doing so (you can always cancel if a better deal arises) I grabbed a room months ago just to make sure I had one fairly close, as CII most sold out and was tricky finding anything within a few blocks of the convention center.
I kinda lucked out, I'm a diamond VIP member with the Hilton chains so I was able to grab a suite at the Hampton Inn for only $134/night!!!!!!
Kitchen, living room, bar, refrig, 2 bedrooms, jacuzzi, the works !!! ;^)
