I was there yester day for my stamping... there was little crowd 20% to 30% of the chairs were occupied on a big floor. For PP stamping token started with CXXX, the max I saw was C068 yesterday. Only 2 families were left on the floor when left, i.e around 12:05pm. (I reached there at 10:30am).
I was impressed with facility on the 3rd floor. Been to 13th floor for iEAD which was ok.
