Unfortunately, we can’t. We don’t have the staff for a full time box office, and it’s better for you to exchange them. For one thing, if the new night you wanted is sold out, you can decide which available night is your next choice. It’s actually easy and quick to exchange your tickets yourself, you just need to do it at least 24 hours before the original tickets’ performance. Go to the Information column on the right of the Buy Tickets page, click on “exchange tickets online” with your purchased ticket code handy (it’s on the emailed receipt), and you’re off and running.
