I think I know what is going on. You aren't buying a Series ticket, right? I went back to the site - Section 11 is available if you buy for the whole tournament - Section 12 if you just pick one day (I picked Thurs).
What club do you play at? I met a huge group from Makati that used to come to Shanghai when it hosted the Tennis Masters Cup from '05-'08. They play at the Polo Club.
Stop by Section 11 - I'll be in the front row all week. Probably have one of the RF hats on.
