This is mosly about the Vendor portion. I went with my kids to see the costumes and the merchandise. We sat in on a couple of the interviews, but not being a "Trekie" . . .
The Vendor portin was very cool. There were many people in costume, even got to see some of the actors. Everyone was friendly, and seemed genuinely interested in what show we liked best.
I think next year we will try to take in more of the "Trekkie" stuff, (interviews, parties, etc.)
