MGM theatre

Anyone have info on the MGM theatre for DC run? Looking at tickets and seating chart. Looks like theyre only selling GA and 300s section, but when you look at a picture of the seating in the theatre there’s a 100s section. Are they collapsing those seats for more GA?

Anyone with other tips on the MGM much appreciated.. ie is balcony a good seat if you’re row A/B/C

Thx
