Dear Sir/Madam

I am Meirince from Jakarta. We are planing for holiday to visit Hongkong, Shenzhen and then to Macau June 2009 with my brother, sister and friend families with total 17 person. Kindly advise me how to get visa for all of us? All of us should come to your office or is it possible only one person arrange all of the documents to get the visa? Thank you
