This was a cheaper ticket because it had an obstructed view with the pillar, this seat is at the end of the aisle and the pillar just sits in your view of the centre of the stage. These tickets were cheaper than the regular ones because of the obstructed view - this one is probably the least favorable seat but N6 and N5 had better views for the same price as the N7 ticket

Bought this as it was a cheaper ticket - it was labeled as having an "obstructed view" with the pillar in the way but it was still a very decent view and for a good price!
