I am concerned that Row 27 would be a bit obscured by the railing in front of you. I chose Row 21 with the idea that I can stand up without blocking anyone because it's right below the wheelchair platform. I was accustomed to Row 33 on the sunnyside, I figure that's right around the height of the wheelchair platforms.
I was hoping to get 4 seats in Sec. F, but F and HH were pretty well picked over above Row 20 when I selected today. Instead, I got 6 seats in Sec. EE Row 21. If I couldn't get Row 21, I was going to look at Rows 28-mid 30's.
If I was picking later, I would strongly consider lower rows if that's what it took to get a benchback seat. Looking at Sec FF for ESP, there are buyers as low as what looks like Row 6 in Sec FF and H, and ESP buyers have more access to find out if those seats will have a good view.
