Have only been on 328 as pax, and even then did not attempt to visit office, nor (on 2 75 min flights) did I see anyone else do so. If you have a camera and are cosidering taking piccies beware- put it in your pocket as there is not room for hand baggage anf it all goes downstairs - annoying when you're flying over the QE2 on its 30th birthday (also colourful tulip fields around AMS in spring/early summer).
