As mentioned above, must get an Octopus card for each person as you use it to pay for 95% of all public transportation and some purchases (McD's, 7-11, other chain stores, etc.). You can get them right at the airport when you head out. You can load the card at anytime anywhere at 7-11, Circle-K , etc.

There are many places to see in HK, but 2 of the MUST SEE are the Peak at night (take the 100-year old cable car up, one of the steepest climb in the world, but it is a freaking long lineup as it is a tourist trap) and ride the Star Ferry at night (and walk the promenade on the TST side). You will see the harbour and the lights from both sides...

One more neat thing to do is to take the tram on the Island side. It is over 100 years old, and it goes super slow, but it is unique in its way when you sit on the upper deck and just let the tram takes you for a sightseeing tour of the busy streets.

Again, just like my advice on the Japanese travel thread, bring local currency with you. Even HK is highly electronic with the Octopus cards and stuff, still the street vendors and many independent stores won't take plastic
