I wouldn't be complaining too much about missing on on 237.
I think the 2 for each row is, as someone said earlier, so TCU can move people around once all the selections are made. Say one accountholder wanted 5 tickets in a particular section but there were no rows with 5 together. One row had 3 and the next had 2 but the seats were offset but 3-4 seats. They could move the folks next to the 3 down 2 seats and then the guy that wanted 5 could have all of his together on one row. Personally, we're getting 6 and I wouldn't mind if they were split up 3 to a row as long as they were directly behind each other but I think that's why they reserved two to each section. I would imagine once a section fills up the ticket office will then contact the folks in that section to possibly move around a few seats. Once those get situated they'll open up any remaining seats so, theoretically, someone with a relatively low PP ranking who is buying only two seats could end up with really good seats.
