Aw, just the one? There's no chance that my boys can be sneaky and try to weasel in to see workshops that they weren't signed up for, is there? Partly because I want to play with ALL THE SHINY YAY, and partly because... man, it would suck to be the person who spends an hour working on a workshop spiel, only to have, like, one person show up because everyone else is over there at the other cool workshop instead.
