You can get in for free and even get a travel stipend if the company chooses you to become one of the Talent Show acts, though. Twitch has issued an open call for anything worth showing on stage -- it's removing categorical restrictions this year -- so long as you regularly stream under the Creative umbrella. If you're attending either way, you may want to take advantage of the hotel booking tool on the event website. It offers discounted rates for the TwitchCon weekend (October 20th to 22nd), but only on a first-come, first-served basis.
