I have waited in the queue for over three hours now and have still not gotten in. People have reported entering the website well after noon PT and got in to buy tickets after a few minutes. The 20 ticket limit encourages scalping. This process is incredibly punishing to honest fans that just want to attend - this ticketing system is extremely unfair and glitchy. Anyone who was online waiting prior to tickets going on sale should never have to worry about tickets getting sold out before even getting a chance to buy, especially when others log on late and can waltz right in. Very, very, disappointing.
The event organizers should be absolutely ashamed. This isn't some third rate budget convention - DO BETTER. I expect more from an official Lucasfilm event.
