Hi Peter,
I have just sent you a message about Shanghai. Your reply will be much apreciated. Meanwhile about Hong Kong I confirm Cyberport is a very good spot especially for incoming ships. Perfect from sunset till about 14.00hrs. Then the sun is against you. However the traffic is such, 6-7 hours spent at Cyberport in the morning is sufficient I think. For outgoing ships, Cyberport is also fine, but you need a very good 300 mm or (better) a 400mm to really catch everything. I tried to find other places, but could not find any. But Cyberport is really good I think so next time I am in HKG, I will go back there.
