I sat in BB109 which was right next to the little conductor booth - I think they took out seats 107-108 to accommodate it so BB106 should be the opposite side of where I was sitting.
While it was great to see the actors close up, there were a couple of issues:
- the bright light from booth can be distracting (I found myself gazing at the sheet music and the dialogue cues lol)
- there are some set elements that descend from the ceiling that might temporarily block the view when Jesse and Winnie are in the tree. I'm really short so I had trouble seeing Winnie's frog (upstage?)
- a fog machine is used and it reaches the second row but I wasn't bothered by it. Apparently it bothered the girl in the front row because she pulled the collar of her shirt over her nose/mouth.
Overall, I didn't mind the issues I listed and wouldn't hesitate to sit there for Tuck again. Hope that helps?
