Well it has been a decade since I last went, and I just reserved a room at the Hyatt for Friday and Saturday night. June 27th-June29th. I seem to remember that the queue for walk-in registration was always A LOT shorter and quicker than the one for people who had purchased advance tickets. Has this changed? Do you recommend prepurchasing? Sat. and Sun. are the only days I'll be their. Does it sell out? Is it uncomfortably overcrowded? I have absolutely no interest in obtaining exclusives or meeting guests, with the exception of Warren Ellis and possibly a BSG actor. I'll be flipping through long-boxes in the dealer room.
