Been awhile since someone posted on here, but I'll add my comment on here. If you want to see things up close, see how things work, or see a different perspective the front is the way to go, especially if you're off to the side. However, if you do not want the "magic ruined", or things to be less obvious and more of a wow factor it's definitely best to sit in the back.
When I first did the show I was not only very much in the front, but off to the side, so I saw a lot of pieces moving into place, however, at the same time I got to see the action more up close and certain moves and actions looked really cool from that perspective. I really like behind the scenes stuff so I personally liked it. The show stopped even at one point (due to technical difficulties) and person who talks to you in the beginning even pointed out an Easter egg for us that was on the screen currently. However, I just watched the show again today (I think it's my third time now) and I was more in the back and dead in the middle. And it was great, but in retrospect I feel if someone truly wants the best experience they need to sit in the back. However, what I mean by that is as their first time. Because while it was cool seeing it the first time I think regardless of the interruption I feel I would be more astonished if I were in the back as things would not be as obvious and would blend in more.
I feel after you see it once it doesn't matter where you sit, you kind of have an idea maybe after the fact of what is happening and how things are done even if you're in the back after the show is done and finished. And while it's always good to see everything from a distance so you catch it all, especially at a show like this, I feel it's very crucial to catch it from the very back as a first timer.
Unfortunately we cannot pick out seating and as I said it's not the end of the world if you're in the front. However, for those who plan to not see it for awhile once things "come back to normal" what I recommend is that you hang out off to the side while everyone is piling into the seats and once it seems a row in the back would will up about half way then enter the row. This is something I used to do regularly in order to ensure I got the middle seat, as no matter how much you want to try to sit in the middle, the TMs are going to keep pushing and asking you to move down.
