The easiest way from the airport to the hotel is by taxi, which will take about 35 minutes and cost about HKD300. Note that drivers take cash only (rather than credit cards) and you should take RED taxis, which can take you to anywhere in Hong Kong (blue and green taxis can only take you to some other regions).
You can exchange HKD at the airport.
