The seating is too tight even for me and I'm not a big person. I bought tickets 6 months in advance and paid $400 for 2 tickets to get the best seats in the lower circle, only to be informed when we tried to go in that we had to go to the ticket office. There we were told that they were giving us different tickets for some reason that was not explained. We objected to no avail and were made to feel it wasn't anything we could do except sit wherever they decided to put us. That's the last time we will go back there.
