Actually, we more than just "survived" it. The weekend was a smash success. DH, DS, and I helped DD find her friends, then we went off and enjoyed the convention. There were certainly some strange people there, but also a ton of families with kids. We left the convention in the afternoon but stayed in the city and had lunch.
Auntie -- we did see some folks who were most likely Furries, but no one was doing anything inappropriate. Apparently there's an "over 18" zone at Otakon, which is more geared toward gaming and anime than strictly comics. We have until late next summer before we have to deal with that!
My DD officially said it was "the best weekend ever" and we are "the best parents ever" for working it out that she could attend and for making her an awesome costume. She was the only one at the entire convention dressed as her character, and she was getting a lot of compliments. Not bad coming from a 13 y/o!
