I think Andrew enjoyed the airshow most - at least seeing the actual aerobatic shows and aircraft cockpits. Luke and Abigail enjoyed the souvenirs and face painting more than anything. We lasted four hours at the airshow and I was thankful the children didn't tire or complain (well, at least not until the last 30 min. or so).
Wait, I need to correct myself....the shuttle bus ride back to the parking deck was BY FAR their favorite part of our outing. Who knew?
