If you plan to visit all seven of Hong Kong's main museums -- the Hong Kong Museum of Art, Hong Kong Museum of History, Hong Kong Space Museum (excluding the Space Theatre), Hong Kong Science Museum, Hong Kong Museum of Coastal Defence, Dr. Sun Yat-sen Museum, and Hong Kong Heritage Museum (located in Sha Tin in the New Territories) -- you can save money by purchasing the Museum Pass for HK$30, valid for a week and available at any of the participating museums or Hong Kong Tourism Board Visitor Centres. Note, however, that museum admissions are free on Wednesdays.
Keep in mind, too, that municipal museums are closed December 25 and 26, January 1, and the first 3 days of the Chinese New Year. Private museums are usually also closed on bank holidays.
