My daughter and I sort of went. We didn't get tickets for the official event because we couldn't be there the whole weekend. But, we participated in a couple of events that didn't require an admission ticket. We volunteered to help with a scavenger hunt and she went to the karaoke night. We also attended Joy's concert (which was excellent!) and did a trolley tour (Cullen Moss was our guide.) We haven't gone through our pictures yet but if I find anything worth sharing, I'll post again.
For many reasons, I think this looked like a better quality event than the others that have been held in Wilmington. I love that this one heavily involved the crew. They also appeared to make the cast a little more accessible. If you are on facebook, find their page and look at the pictures they've been posting, to get an idea. We did attend the eyecon event in March, which is the only one James Lafferty has attended to date. Prices for both events were similar, but I think you got a much more personal experience with the Inside OTH event, from what I could tell.
