From the Paizo site:
PaizoCon returns in 2013 for 3 days of all the hot Pathfinder action you can handle, now in a new location! Gaming, panels, workshops, costumes, and loads of Pathfinder fun await you at PaizoCon 2013. Meet-up with community members from around the world, as well as Paizo staff, and dozens of hobby gaming’s veteran authors, artists, publishers and designers.
PaizoCon 2013 is three non-stop days of gaming, panels, workshops, banquets, and (most importantly) fun! Rub shoulders with your favorite Paizo Publishing employees and freelancers and game with your favorite people from the paizo.com online community.
3-Day Badges are available for $50 in advance ($55 at the convention). In addition, the ever-popular Paizo Preview Banquet will be held on Saturday, July 6 and tickets must be purchased separately. Banquet tickets are $25 and are limited!
This year, PaizoCon will be held at the Seattle Airport Marriot, conveniently located next to SeaTac airport. The PaizoCon room special during the convention will is $109 per night (single and double occupancy) and rooms in the PaizoCon block must be reserved by June 12th, 2013. Note that purchasing a ticket does not reserve you a room (or vice versa). We encourage all of our attendees to stay at the Seattle Airport Marriot in order to remain close to the daily gaming action! Please visit our FAQ for information about the Hotel (such as parking and internet access rates) and the surrounding area.
We’re also hosting a Paizo Preview Banquet to show off upcoming Paizo and Pathfinder products, as well as super-secret things that we’ve been dying to tell you about! Additionally, members of the Paizo staff, PaizoCon 2013 Guests of Honor, and other hobby industry luminaries will be seated throughout the banquet hall, giving attendees the opportunity to chat with industry professionals. Banquet tickets are $25 each and must be purchased separately. You must purchase a PaizoCon 2012 3-Day Badge in order to purchase tickets for this event. This event is limited to just 350 attendees, so act fast if you’d like to attend.
