If you think the Christmas decorations are going up early this year, get this: We're planning now for Comic-Con International in San Diego next July! It's July 23-26 to be exact, with a Preview Night on the 22nd.
Last month, they had Returning Registration where folks who were there last year could compete in the lottery for a certain number of the tickets for the 2020 event. This month — on November 16, there will be Open Registration where anyone who already has a Comic-Con Member ID can vie for another certain number of tickets. Many of them will not succeed because there's a lot more people who want to be in that convention center than the convention center can hold. But if you're going to try, read this page well before 11/16. And if you need more prep, my friends at the The San Diego Comic-Con Unofficial Blog (not affiliated with the con itself) have prepared this page which will tell you more.
Also, if you'd like to know more about the history of the convention, the con has posted some highly informative articles on this website. These were written for the souvenir book last year and even I, a person who's attended every last one of these kosmic kaffeeklatsches, learned much from them. If you haven't read Bill Schelly's massive overview of the con's history, which I recommended here before, make sure you do. It's the first of the links on this page.
Lastly, if you can't wait for Comic-Con (and/or can't get a badge), WonderCon is April 10-12, 2020 at the Anaheim Convention Center. Run by the same fine con-runners, it's kind of like Comic-Con Lite. That means that instead of being twenty-five times too big to see and do everything you want to see and do, it's only about ten times too big to see and do everything you want to do. Some folks prefer it to Comic-Con because it isn't quite as overwhelming. And some folks prefer it because it's fairly easy to get a badge for it if you act when they first go on sale.
They haven't yet. I'll try to let you know when that date is announced but you might want to keep an eye on the website, most of which still displays info on the 2019 show. I think that's everything for now.
