Before you leave Hong Kong airport for your hotel (or other final destination in town) there are a couple of things you should do. These two important steps will turn you into a real Hong Kong person and make your trip very much more interesting.
Before you can do either of these things, you will need some cash. Hopefully you followed my advice and didn’t do any money exchange in the arrivals area of the airport, their rates are generally terrible. The best way to get cash in Hong Kong is to pull out your trust ATM / cash card and make a withdrawl. At current rates, a $1000HK dollar withdrawl is about $130 or so US dollars. Thankfully, there are a number of ATM machines right in the airport, which makes things a little easier.
The cash machines are generally located in the area between the A and B exits, near the central elevator / escalator complex. If you came out of the A gate, that will be to your right down the concourse, and if you came out of B, it’s to the left. All of the stores and services are located along the wall between the A and B gate exits, so as you walk along from the A gate you will have shops and banks on your right, and restaurants on your left (congrats, you just saw your first Hong Kong McDonalds!). There are a couple of sets of ATM machines along the right side near the elevators. I think they are a Citibank and an HSBC, but not to worry, they have global access to most other banks. Withdrawing cash here will likely get you a much better rate than trying to exchange cash at the airport. You should probably withdraw a couple of thousand HK (which is only $250 US dollars) as you will need to spend a bit in the next few minutes to get yourself organized.
Now, for Hong Kong step 1: You need an Octopus card. Why would you want an octopus on a card? Well, actually, in Hong Kong the Octopus card is possibly one of the single most useful things you can have. It’s you method for paying for trains, buses, subways, and even the airport express train. So in that regard, it’s sort of a transit pass. But it is much more, because pretty much every small convenience store (7-eleven, Circle K, Vingo, and others) will have a machine that lets you pay for your purchases by deducting right off the Octopus card. No more fighting for change! You will actually be very surprised all of the places you can use it instead of cash, from McDonalds and KFC to local restaurant chains like Fairwood or Cafe Coral. You can use it to access the cross harbor ferries, you can even use it in some places in Shenzhen in mainland China. It’s a value added storage device that will keep you from ending up with a pocket full of change, and also help you to not slow down lines in convenience stores!
