There are a total of 22 seats in Section 121 Row 11 at the MTS Centre. As you face the action, the lower numbered seats are at the right side of the row, while the higher numbered seats are at the left side of the row.
There are better options on the lower level than the 100 Level Corner sections. Closer to the stage than the 100 Level End sections, but do not have the same advantage of head on view to the stage, and will require more head turning during the show. As such, this is the best place to find cheap 100 level tickets for a concert at the MTS Centre. Sections here contain up to 16 numbered rows of seats, with the lower numbered rows located closer to the floor.
