You do not need to have a ticket to Blizzcon to attend the party, which will be held at the Anabella Hotel on October 20. There will be awesome swag, a chance to meet your favorite personalities from Gamebreaker, WoWInsider, and sites like Tankspot and Zam. It sounds like it is going to be a ton of fun and if you're not in California, like me, you can watch a live stream of the party on Gamebreaker.tv!
There's even a Facebook event page for the party. So, if you'll be in the Anaheim area on October 20, even if you're not going to Blizzcon, check out the party, starting at 5pm PDT.
