Uber Arena — Eisbären — as your buyers see it
A real big-arena hockey bowl (Uber Arena, Berlin) built to scale: 13,784 seats around a horizontal ice rink, with north-side Premium sections 101–104, a continuous Lower Bowl 201–220, an Upper Tier 401–421 wrapping three sides, east-end Loge suites and wheelchair positions.
It exists because real arenas are not symmetrical — the section numbering, the suites and the accessible bays all have to be modelled as they are, not as a tidy diagram.
Try finding a wheelchair position, re-pricing the Loge suites, then previewing the arena as a buyer in 3D.
