I am soon to fly to HKG for the first time - I'll be arriving at 9pm on Dragonair Business Class.

In no particular order, I will need to:

a) Visit an ATM for some cash
b) Pick up an Octopus card
c) Visit the Arrivals Lounge for some food
d) Take the A11 CityBus (it stops right outside our hotel in HK Island and saves multiple train transfers)

I understand that HKG is pretty big, and as it's 9pm with heavy luggage I can't afford to trek back and forwards across the terminal trying to tick these things off my list. So, can anyone guide me on the best way to achieve this with minimal hassle? I'm not sure where the A11 bus-stop is in relation to the Arrivals Lounge, and whether there will be an ATM and Octopus card machine near to the bus-stop.
