It's so frustrating how you can't choose. Honestly, the whole set up to get tickets is awful
It made sense when they first were released I guess, that way people could kind of fish around for dates, but now they should just make them available on ticketmaster the normal way. I also hate how, whenever you release tickets, it's a whole process to get back to where you were. Especially if you were looking at further months.
One trick if you want to try and fish for tickets before box office - grab the tickets you keep getting on your phone and hold them in your cart while you search on your computer. That way it will be forced to give you new tickets. I kept getting this one seat really far to the left - like the absolute last seat to the left - so I did this and got a slightly further back row, that was more center stage. Of course, you're really limited to only two or three times (unless you have a million computers, but I reckon at this point ticketmaster would ban your ip. So id safely only use two or three). Still, at that point, I usually take it as there really isn't any better seats available. Sometimes ticketmaster won't give you the *best* available seat though, in my opinion. (Ex: I got f17..then went on my phone and got c10. This was literally today, so i doubt anyone was holding it randomly).
The ticketmaster order line is pretty unhelpful, but I've never tried dealing with the box office themselves. Waiting til that close you run the risk of many of the good seats being sold out though - or perhaps your whole price range in general. While they do discount some of the seats (i believe) it's usually the most expensive, so I think it still ends up being 199. This is just hearsay on my part though, so I'm not sure!
