Good day! My family and I will go to Hong Kong On December 8-11, 2010. How is the weather during this time? Should we bring jackets/sweaters? We are also planning to have a day tour in Macau? Is it going to be cold there too?

I would also like to buy a new camera in Hong Kong. Which stores do you recommend? The ones who sell genuine stuff? I don't want to spoil our trip by accidentally buying a fake camera.

Thank you very much!
