I sat in Row Q and was THRILLED with the seats--- no problem with the overhang... Not sure what it looks like from T, but I don't think there should be too much of a difference.
When I was looking at tickets in rear orch, I noticed that some seats had a partial view warning because of the overhang. Did Ticketmaster warn you of such when you purchased the seats?
I really don't remember seeing a railing in front of row L --- I went down to visit a friend in front orch- I think there is just a large space/aisle....
So, that was the Drowsy Chaperone. Oh, I love it so much. I know it's not a perfect show...but it does what a musical is supposed to do. It takes you to another world, and it gives you a little tune to carry with you in your head for when you're feeling blue. Ya know?
