When do we need to start looking for, I dunno, tickets
Tickets are for sale now On the PaizoCon main page. You'll pick up your actual ticket at the door. Have your ID to prove who you are.
Rooms are also available through a link on that page. Banquet will usually sell out, and the room block rates (if not all rooms) will also sell out. It's handy to be in this hotel instead of elsewhere because morning sessions start early, and some sessions run until midnight. And there is often limited time between sessions if you schedule your day full.
schedules?, lottery-um-explanations?, um, event maps?
You won't see most of that stuff for quite awhile probably. I'd guess February - April time frame. The schedule will be posted and then you'll have a week or so to prior having to finalize selection of events you want. Here are a few types of events
1. Lotteried events, prized spots at the table with various Paizo personalities. You prioritize which events you want most and then using fairy magic and what seems to be rather fair process you get assigned events. Don't expect to get many of these, though my favorite things have been the more random, unexpected games.
2. Seminars and workshops- For the most part there are enough seats to get into most of these.
3. PFS and Adventure Card game. Most slots have plenty PFS and ACG games available, so, unless you need that "one last module" to round out the season, you should be able to fill up your schedule with these.
4. Friday and/or Sunday evening are usually a 7-Midnight PFS Event (playing the Aspis, or the whole room working together on a quest), Saturday evening is a banquet with Paizo News.
You'll want to pay attention for when the lottery happens (just watch these forums, it'll likely also be posted on the main blog, probably an email to signed up people), more information will be available when it comes out. The main thing is to ACTUALLY prioritize. Mark your number 1, then a couple of number 2's, etc. When they assign you an event, if you have 10 things marked #1, you'll get a random one. In any case, there's a great deal of good info here. here's more info on the lottery and other things.
