I've been to SDCC in 1996 and 2006-2012. I had fun in 1996, but if I hadn't been obligated to go the other years for work, I would not have, at least not after seeing what it had become in 2006. Never again if I can help it. It's by far the worst convention I have ever been to, and I have been to a lot. I have no idea how people spend thousands to go every year and feel they got their money's worth. I don't feel the organizers have any respect for the attendees' time or money.
