Definitely go - second floor seating will be just fine. In fact, we went a few years ago and had balcony seating and loved it. This year we are going again and I was actually disappointed to be told that there were no balcony seats left when we wanted to go, so we will be on the main floor (Category 2). IMO, balcony seats will be better for you due to unobstructed view - especially for the kids.
