I was just there last April on a school theatre department trip and I got to see POTO and go backstage after the show - most amazing experience of my life! As for good vs. bad seats, I was in the top balcony (yay what kind of seats student groups can get). Even though I was super far from the stage and performers were tiny tiny, the magic was oh so alive for me the entire time - I literally was on the edge of my seat from the moment the chandler rose at the beginning. If you look online when buying tixs maybe you'll be able to find a good map of seats, but in my opinion there will be no seat that "ruins the magic" because there is way too much magic!
