I agree with this, but that means spacing the seats out which would mean less capacity, which means less $$$ in revenue, unless they wanna raise tickets prices by quite a bit
It would be very difficult in their current location, because first you'd have to tear it down (which probably takes a year at least), and then build a new one (which would take another year or two).
The only way out of this is a total refurbishment, and thats also not easy to do. People wanna see more open sky, plus natural grass, plus a bunch of other things. I just dont see how they can do all that
