Had Category 3 in May. All the seats are upstairs. DM's seat was fine. Unfortunately, I was right behind a pole and there was a whole section of the stage I could not see. This did not completely ruin the show, however, since they move all over, both on and off the stage, including upstairs.
I also did not like how the tables were set up. You eat facing away from the center of the room and then have to turn around to watch the show. I personally would not do Category 3 again.
