If I purchased tickets for a show on December 16th, would I be able to change the date to December 23rd for the same time and same seats? If so, how do I do this?

Call and leave a message if no one answers. The box office is open 6:30p-8:30p m-th and 9a-12p Saturdays starting a few weeks before a show's run, as it's a volunteer organization.

I agree with Lane. If you leave a message, they are very good at getting back to you and they are extremely flexible.

I tried calling them all day.... nobody answers

It depends if the seats are available, but they are pretty flexible if you call them...

Call the theatre and ask
