I was here yesterday. Had a really fun time, I just hope they are more organized today, my kid was disappointed the dude setting up the video gaming area didn't show up until 6 hours late, but the Amtgard arena more than made up for it for him, I think.

Just be prepared for lots of blank stares when you ask the booths to fill out your scavenger hunt papers. Bring a pen so they have something to sign it with for you.
