If an actor/actress has announced their final performance in a given show and you buy tickets, and then they end up extending and moving their final performance, would you be allowed to exchange your old tickets for the new date?
Good question. I've done this twice for Sutton as Millie. Went anyway in Nov, gave them away in Jan., and saw the real thing in Feb. I didn't care much, since I'm a big fan, but I was wondering just as well.
