It's great to hear you are making the trip up! Unfortunately Origins this year has really had bad web site arrangements. You can buy a badge and look at what you want to sign up for but the actual sign up has not happened yet. Last year was also a pain in the ass and I ended up buying generics on site and used them for many of my games. I have planned out what I hope to sign up for with back up games selected in hopes that on line sign up will happen.
I'm a local, I've gone to the con every year its been here. If you have any questions I'll answer what I can!
