I will be attending a conference in Zhuhai, China from 26-28th December 2009 with my colleagues. We plan to go to Hong Kong then Zhuhai and spent a couple of days in Macau. My questions are:

(1) Do I need to provide hotel reservation vouchers for all three cities...i.e hotel in Hong Kong, Zhuhai and Macau?

(2) Since my friend did the hotel reservation ( we are sharing room), the reservation is under her name and not my name. Is it acceptable for visa application?

(3) Besides air ticket and hotel vouchers, what other documents do you need for visa?
