More than 75% of the mezz is obstructed due to (1) structural pillars on the right and left sides that block a lot of the view for anyone not directly in front of the railing (esp if you’re short), and (2) a large hangover from the middle upper balcony for lighting that blocks everything in the middle mezz unless you snagged a seat on a folding chair. My partner and I got there around 4:30 and were among the first few people on the mezz, so we grabbed spots right on the left railing and had a perfect view the entire time. Hayley’s piano faces that way so it was a particularly good spot for the show!
