348 will give you some steep steps to climb so have caution. Row 4 is actually the first row so shoot for as close to it as possible. Cheap tickets. If you don't enjoy your seats up there, you'll have no one to blame but yourself. You get what you pay for.

Nothing about the Pepsi Center stands out to me and really grabs my attention. The facility is extremely clean but it lacks something that truly defines arenas. History, maybe?
You can't beat it's accessibility, either by light rail, cab or driving yourself (cheap parking), the Pepsi Center is easy to get to. You can even walk from your hotel (we always stay at the Hilton Garden Inn on Welton Street; cheap rates).
