Entrance ticket fee for Madame Tussauds is 160HKD for adult. Through ticket for the wax museum and single way Peak Tram is 170HKD (180HKD for round trip). I think this is better. Most of other museums costs 10HKD for the entrance fee. It is hard to tell how much money to take. Bring you card and take some cash. Hotels costs and meal costs are hard to predict. Disneyland ticket: 350HKD per adult, Ocean Park: 280HKD per adult, Nging Ping 360 cable car: 107HKD per person. You should prepare 100HKD for one day's food, just ordinary food. Must ost more if you go with your family. Prepare 100HKD per person for the traffic!Hope it helps you some.
