Adding to what @voteperson said... Yes, you should remember that TDF does not assign seat locations. That is up to the box office.
However, the seats ARE supposed to be in certain price zones. for instance, if I allocate seats to TDF that are $50 at full price, they will appear on the TDF site as $25. So their pricing is base on the price zone offered to them. Broadway shows often get away with seating TDF ticket buyers outside of the designated price zone because TDF always does better when they offer Broadway tickets. But I once got a stern warning from TDF because in the off-bway theater I worked for, one of their buyers was sat one row behind the "correct" price zone. (I had given them an aisle seat, which I actually deemed to be a better location than what was left in the correct zone which was closer but on the side of the house. Also the price difference was minimal, maybe $7-10, and it was about 150 seats in the house with no bad view. The company shouldn't have even created multiple price zones tbh, but i digress). But the patron pulled up her phone to look at our website after being seated and noticed she was a row behind what the ticket was worth and complained to TDF. Still can't believe she complained about a central aisle seat.
Anyway, the point being that you can sometimes figure out the possible areas you would be in a theater based on prices (and we all know that most broadway houses try to price as high as possible, so something you deem to have a partial view on the side orch might still be an $80-90 seat). If you get a better location, then the house was undersold and its your lucky day b/c the box office used TDF to fill in some gaps in better locations.
