It's at the Convention Center/Hyatt in the north Downtown area. Pretty easy to get to really, even from Cinci.
And, yah, I think $45 is steep for one day. As I recall, I think there was a one-day rate that I paid last year that was only like 15 or 20 bucks. I think I will send in my reg tomorrow (it's $40 if you preregister), then I'll blow the extra 5 bucks on something stupid like a gundam keychain.

( < My only souvenir from last year. Draxy dropped millions on beautiful cels, and I bought a gundam keychain! hahaaaha! Well, I did spend some money on Godzilla items for the boys too.) Even though I think $40 is steep for one day's attendance, I think you would have fun just walking around, soda. Just to do some major people watching was worth the price of admission.
