I'll probably be going. I'm a minor, though, so I can't share a room.
I don't know if I should wear the same SWR Reisen costume I've been wearing or if I should buy a Yukari, Marisa or Alice costume. I'm leaning towards the latter because I dislike wigs.
Last year I attended the Touhou panel with a friend dressed like Alice Liddel from American McGee's Alice. Okay, not exactly that, but it was the closest resemblance I could think of. I don't know if I'll be able to stay all three days this year, but I hope I can.
