Don't expect to see much if you want to get cheap tickets. I picked up cheap tickets, got drunk on wine (whilst being judged by the nuns) and then slept through the first act. The second act was phenomenal and then I left in the next intermission for pizza and meloncello at Piz.

10/10 would recommend paying full price if you want to see more than the back of old people's heads/ a beautiful historic building.
