I was in between 7 & 8 right at the circle and I loved it there. I uploaded a pic on my page of how close she was. She totally performed a whole lot there.
In my opinion, although I didn't get GA tickets, I think 1,4,5, and 8 are the best that is where she was at the most, especially 4 and 8, but to me, all but 10 and 11, they are all amazing spots.
At Connecticutt and Philly the early LM people all went up front, and then the GA people slowly filled that area. Unless you want to hang out for the love, it's probably not necessary. have a blast! Best performer in the history of the universe!
I stood at 8 and spent the whole show running around under the catwalk and followerd her to 9 4 and 3 it was the best I suggest you walk around throughout the show!
The corner of 8 and 9 was wonderful! I got so many good pictures, and she came around multiple times, you get a good view of the stage, the corner of the runway and when you turn around there's the piano! Plus lots of room to dance :)
