I saw the show from about the 4th row from the rear in the balcony. It didn't bother me. (I must admit it helped that the seats in front of me weren't occupied, and I could lean forward a bit.)
Everything is pretty big for the show. I wouldn't worry about it.
I would have killed for the last row of the Balcony instead of the last row of the mezz, I missed half the action! I had to hunch down just to see the feet of Lancelot and Herbert for the whole castle scene!
If Lincoln were alive today, do you think he'd be pleased with his tunnel?
I agree, last row of the balcony is better then the last row of the mezzanine and they are much cheaper seats. You are a bit high up, but it's a small theater so not too bad and you can see everything. It's better than most partial view seats which are also more money.
The show is funny, regardless! I have a ticket for February, and I'vs sat all over the theater for this show---you don't miss TOO much, even in partial view. Enjoy!!
