The most frequent questions asked in the forums have to to with obstructed views in sections D & E. A close second has to do with seats in the Pool Circle…especially for lease events.
When a non-LA Phil sponsored event (called a lease event) is held at the Hollywood Bowl the boxes in the Pool Circle are replaced with folding metal chairs. Usually there are five section (A through E) with 7 rows of chairs. Sections A & E start at row 3. I say usually because different bands have different requirements like an extended stage for example.
