It's true there are a lot of great spots to sit to view the show. I would recommend a few different showings to be able to get a chance to view the show from all those seats. The front row is absolutely fantastic, the first row of the section section on the main floor is great as well, the front row of the balcony is also a very different experience.
Won't say why, but you will probably want to go in on the balcony the very first time, and decide what seating the next time-its a show that is absolutely breath taking, and you will want to see a few times.
