Like I said, there are no pictures of people (except me, at home in my costume) because I went alone and was too shy to ask anyone. But I'll post some links to pictures I found online even so close to the event.
I worked for eight hours (four hour shift on two days) in the large cloakroom, which was pretty easy work for the most part and gave me free entrance. And I could talk to people, which was also cool.
