Got there at 10:00 on Saturday, spent two hours finding a place to eat and getting back, then spent FIVE HOURS in line to get my day pass. Wandered around for three hours, saw a ton of cool shit, bought a t-shirt and a few art prints (and nearly got a great deal on a Beast Mode Unit 02 Revoltech, but the phone the woman at the booth was using to read cards was too slow to put through the transaction, and it was still enough money that I wasn't committed enough to get cash), then took off because my buddy had to be back to work. It was a lot of fun despite all of the wasted time, and we're definitely going again next year, probably for more than just one day.
My Youki cosplay turned out great, although I kind of botched it by forgetting the shoes I was going to wear and the cord I was going to tie my swords with, not to mention not having a Myon or a wig yet. It will look much better next time.
Saw a handfull of other Touhou cosplays, although I didn't really get the chance to talk to anybody. Next year! Next year things will be different.
