I have booked 2 tickets for Mike and I in Left Section, K1 and K2, there were chunks of seats left there, but I think spaces are getting limited apart from side balconies. Prices range from about $45-$80.
Would love for people to come and make a group atmosphere, maybe meet before for dinner somewhere.
This website is good for interactive seat map and ticket booking.
Anyway, let's see how many of you would be interested. :)
