We came here for a free tour in mid-October. We didn't have high expectations but we were really delighted with the caliber of the tour. Our guide, unfortunately did not have a name tag on, and I didn't think to ask his name, but he was the one male docent at the time and he did a wonderful job guiding us through the theater.
I hope to someday be able to see a show there, especially now that we've been able to see so much of the theater (stage, orchestra, balcony, dressing rooms, the vast ladies room etc.). I'd highly encourage anyone who's available on the Tuesdays they offer tours to attend.
