Agree with all Leezyjet has written about HK - some other tips:
- if you're on a budget... consider the YMCA for accommodation - decent rooms & prices, great location, close to the Star Ferry and the waterfront for views across to the island.
- a trip to the races at Happy Valley is also well worth it if they're on while you're there. Hong Kongers are nuts about racing.
- and if you want to get away from it all, Sai Kung in the New Territories is really lovely and probably the best place to go to for seafood in Hong Kong. There's also a national park there - nice hills for walking and you can kayak and windsurf: you'd never guess you were in Hong Kong.
Public transport there is good - if you're going to be there for a few days, get yourself an Octopus card - you can charge it up with cash and it works on buses, trains and underground and makes getting around hassle-free.
