I had one of those seats -- last row, all the way to audience right. The pillar blocked some upstage action, but for $30 it wasn't a deal-killer for me. I was able to slide one seat to my left for Act I, since that person didn't show up, and then one more seat to my left when someone left at intermission. Still somewhat obstructed, but not bad. Warning, though: It's chilly in that part of the theatre. It was a cold day, and there was quite a draft coming down from the ceiling. I wore my hat and gloves throughout the show.
I did see ushers move an elderly couple to a pair of much better seats, so you could get lucky, too.
In spite of the chill, I enjoyed the production.
