Has anyone seen it with their kids? How was it?? How long is the actual show?

I managed to get seating for the 5:00pm showing on 12/19 with Kirk Cameron (I was absolutely in love with him during the Growing Pains era - LOL.) Since it is the early show, our ressies are for a late lunch at Coral Reef (wanted Le Cellier but it was booked.)

It will be myself, DH, DD7, DD3, DS 6 months. I know it is the early show so there will probably be more kids present than at the later shows, but I'm having second thoughts about taking my kids. I would really love to see the show, but I'm not sure if the kids are too young. If I could manage to sit on an end, is it possible to leave mid-show if my 3 year old won't be quiet?
