I arrived yesterday (Sunday) at 7am and there were already seven people there buying two tickets each, so 14 tickets were gone. Within a half hour, four others joined the line.
I asked about partial view the previous day at the BO and they told me this:
They do not sell those tickets until they are sold out. She said to check back between 1:15 and 1:30 to see if they were sold out yet. If they were, she would sell tickets for $36 (?) each. If not, I'd have to stick around the BO until all seats were gone.
Also, 30 mins prior to showtime for the matinee on Saturday, LEGALLY BLONDE popped up on TKTS.
"The Spectacle has, indeed, an emotional attraction of its own, but, of all the parts, it is the least artistic, and connected least with the art of poetry. For the power of Tragedy, we may be sure, is felt even apart from representation and actors. Besides, the production of spectacular effects depends more on the art of the stage machinist than on that of the poet."
--Aristotle
