sorry to be so dense, but: where on the o2 site are you finding a seating chart?
i do have the one from TM UK, but i'm curious where it is folks are counting rows on the o2 site.
and as long as i'm here ... in the photo on this page: [
www.theo2.co.uk]
there are four sections of tiers visible. i'm curious about the two skinny sections in the middle -
are those part of the 100s or part of the 400s? thanks for any insights ...
