I can't wait for the kaneda podcast about this.
In all seriousness, I went to my first Pinburgh/ReplayFx last year and have never been to the PAPA facility. Pinburgh/was one of the most fun events I have ever attended. I thought the convention center was a great location and there were a ton of restaurants in the area to hit.
I didn't even think of the concrete floors until others mentioned it. Yes my feet hurt, but they hurt anytime I am on my feet for 10 plus hours. I'm going back this year and can't wait.
