The category seating is something new and I don't think it will affect you. I think I read on allearsnet that this new seating begins in January of 2007. Basically, they are now charging for where you sit - the front is more than the back and there are three tiers or pricing levels. Since we will be going next July, I want the best possible seats, category 1, but I also wanted to be able to use our DDE discount on those seats at the late show.
But I don't think the new seating will affect you. Have fun!
