I guess as far as logistics go, I was think of a more volunteer type thing, where it's completely optional. I know for me personally, most of what I do at events is walk around and talk to people, so it would be easy for me to just stay in one specified area and do the same, just let the people come to me. Also, if there were more than one who volunteered, they could do shifts of sorts...

It would also be a great reason to have my significant other fetch me food and drink MUAHAHAHAHAHAH "Sorry hun, gotta watch the booth" lol
