WonderCon used to be in San Francisco…and I really enjoyed it when it was there. In terms of both facilities and location, the Moscone Center was a great place for a comic convention. Unfortunately, the Moscone Center has more conventions that want those facilities than it has available dates, and they also don't make the kind of multi-year commitments that just about every other convention center is eager to make.
This year, the Moscone has been undergoing renovations and WonderCon had to relocate to Anaheim for 2012. They'd hoped to return to San Francisco for Spring of 2013 but were unable to procure dates…so they booked a WonderCon into Anaheim for March 29-31. At the time this was announced, WonderCon officials said they still hoped to secure dates from the Moscone to have a WonderCon there in late '13.
Well, they were offered a slot but it coincides with another major convention in S.F. that has already driven up hotel prices and would make for cramped quarters. So they've announced there will be no WonderCon there next year. I'm sorry to hear that but at least they're still hopeful for 2014.
