My friend and I did the following -
Friday: Junko Enoshima and Drill-less Celestia Ludenburg (most of morning), SnOwman and Feferi Peixes (PM/Homestuck Panel)
Saturday: SnOwman and Ms. Paint (AM), Austria and Hungary (with an Aradia Medigo)
Sunday: Lucius and Narcissa Malfoy (Harry Potter Panel), Junko Enoshima and Drilled Celestia Ludenburg (from 6:40ish to 11? Walking around with a Kirigiri)
We are really looking for pictures of her with her drills on her head!
