I don't think i would want to go to a convention either if i had to try and look after a baby as well, having to try and push past people and if you want to buy things you have to try and get in amoungst the people all around the tables (something i'm not very good at anyway).
Hay liz i think i saw a Yuna but i'm not sure about the rest of you, i would say the most common costume choices were Edward from FMA and the Sailor scouts....and those girls that wear cat ears.
I want to go i Aya but it's more of a big day long thing, i was only at the Expo from 2:30 onwards, it would probably have to be a over night thing and that probably wouldn't be possible for me. If i go though, i definatly want to cosplay (this probably means i won't), all the way home from the expo (except for the times i was sleeping) i was thinking about who i could dress up as and how i could possibly make the outfit, that and wishing i had a portable dvd player to let me watch my dvds and bring me some entertainment on the long drive home.
Also i thought Brighton was up country to, i seem know nothing of our country
