Quoted from Phat_Jay:
I think a service where one arrives at a show with their games, backs up to the door, and someone unloads the games, checks them in, unpacks, and sets them up for you would be neat. At the end of the show, they pack them up, you back up to the door again, and they load the game for you. Moving games around can be a real pia.
I've seen this attempted before for a first year show, though not followed up on. It's a great idea though... even if the owner is responsible for packaging and unpackaging of their games.
