It used to be set up with people lining up each year and spending half of the convention time waiting in line for tickets for next year. Seems like a big waste of time right? Well thank GOODNESS that was noticed so all pre-registration for 2013 will be exclusively online only. (So no one had to wait in a line this year.) whew!
Those attendees who get to pre-register for 2013 are only able to purchase up to 3 badges...and they can't purchase badges for anyone who DIDN'T get to go for 2012. Kind of sucks, huh? But I suppose it's fair.
How this is going to work is, everyone who went this year (whether they purchased a four day badge or a single day badge ONLY) will receive an email in August 2012 from Comic Con regarding a date when pre-registration begins. Another email will get sent out at a later date for others to sign up for Comic Con2013.
I'm sure there is a lot more detailed information on their website and a contact number in case you have further questions that I can't answer.
If you need additional info or anything else regarding Comic Con, hit me up! whoot whoot! ;)
