I can tell you that WikiTree will indeed have a booth set-up in the Expo Hall and it will be manned by Team members, current leaders, members and of course our WikiTreer in Chief, Chris Whitten.
More importantly, I will be there. :-) I will be the one in Orange under the WikiTree signage, wearing a big smile. Look forward to seeing you in real life.
As for classes, lunches and where to stay? The Raddison, Marriott and Hilton are all close to the Salt Palace. Sign-up for as much as you think you can handle - LEAVE time to wonder the expo Hall, because it's huge. If you are feeling the love you can also plan on spending some time at the WikiTree booth helping to spread our WikiTree love. We would love to have you join us at anytime!
