I have to turn down two Halloween party invites if I want to go to the dance at Steamcon (and I might have to skip that too so I can get up early the next morning for the workshop). What was Steamcon thinking scheduling their convention the weekend before Halloween? Don't they know that's a MAJOR party weekend? Common sense should tell that anyone who loves to dress in a steampunk costume probably also loves to dress in other kinds of costumes. And that means they want to be at all the other costume parties that are the same weekend as their convention.
I hope who ever planned this thing comes to their senses before the schedule next year's Steamcon.
