While not a first timer per-say, this year is the first year I'll be a full attendee and not at work all week! My wife won't join me until Friday. I'll be orphaned until then so I'll try to attend the meetup.
It's pretty much a BGG.CON 101 session. I finally put together a presentation a few years ago, so we'll be showing slides with pictures of people who are good to know, who to look for if you have questions, and we'll try to answer those questions before you even know you had them!
