Well done to you all. We went on the Saturday practice day, and being "local residents" qualified for free tickets which were given to those who lived nearby. We were in the stand on the north side of the river, opposite Greenwich.
Felt the facilities were all well done. Sat up at the back of the stand which gave the best view. Incidentally on entry with tickets for the "standing" area we were told we had been "upgraded" to the seating area, but to be honest I could not see any standing area anyway.
Had seen the preparations going on for the spectator areas in the preceding couple of days and a lot went into it.
The video screens and the commentary were good and you could hear and see what was going on, unlike some comparable events. The only real distraction was the chase cameraship helicopter which drowned things out as it passed.
