I've traveled from out of town to NYC and see four or five shows a year for the past 15 years. so that's close to 75 shows. We always do matinees exclusively. In all those years I've only had one occasion when a lead or featured actor was out, Wicked, back when it was new. Idina, Kristin, Norbert, Joel and Carole were all out. Hasn't happened again. So, you see how avoiding matinees because of one instance doesn't make sense? If you went to one evening performance and someone was out would you avoid evening performances?
