Aside from the more affordable pricing, the corner sections on the Balcony level leave much to be desired. The views are less than ideal, and concessions can be very scarce as well (sitting in Section 304 will leave you no less than a 2 section walk to the nearest option, NOLA Popcorn).
The even numbered rows is where you will find the entry tunnels, as well as available areas for handicap accessible seating. Odd numbered sections have a continuous seating layout which start with Row 1 at the front, and extends as far as Row 20 in some corners.
Your best bet here is to stay within the first 6 rows of Section 313. You'll be close to the entry tunnels at the front of neighboring Sections 312 and 314, good concession options are nearby, and you'll be close to the Pelicans team bench.
