Hello! My family and I plan to go to (from Manaila to) Hongkong and Macau (before going back to manila) on April 2010. I want to know how much is the cost if we want to make a sidetrip from Macau to shenzen? Do we still need to get a visa since we are coming from Macau? How much is the boat fare going to shenzen? And how much also is the entrance fee at Windows of the World and Happy Valley?
