What's funny about our theaters in SF is that they are wide. A lot more than one's you find on Broadway. It is easy to have stage seating for SP on Broadway, easier to get too. Here, there is an Orchestra pit in front of it. There is some distance between the stage and the first row. If you were at the Curran I would say it is possible for stage seating and if you were at the Post it would be much easier to do stage-seating there.
Anywhere else, not so much...too much for a walk for people and could be a stretch!
"In the U.S.A.
You can have your say,
You can set you goals
And seize the day,
You've been given the freedom
To work your way
To the head of the line-
To the head of the line!"
---Stephen Sondheim
