I would be unlikely to attend an event like this unless it was close to where I live. I've gone to a few conventions, mostly sci-fi, and they can be a bit hectic. One time Gil Gerard was at one. His table was next to Erin Gray's and I noticed they did not speak or look at each other.
On another note, I've been reading the LHotP subreddit. There are a lot of posts and an active community there. In true reddit tradition, there's some good stuff and there's some not good stuff.
