200 level sections behind the basket are usually the cheapest tickets for a Providence or other basketball game. For the best experience, choose a section that is closer to the corner of the arena (absolutely avoid 201 and 221) and a row that is as low as possible.
The closer you are to the corner, the less obstructed you view will be (by the basket). And the lower you are, the closer you will be to the concourse.
Sections 219-223 are the largest in the upper level with rows ranging from A-T, while sections on the opposite side are the smallest - with some sections containing as few as three rows.
