Hong Kong Airport - Hotel

Hi, my fly is coming at 23.30 - and I go on next day evening to another country. I am looking for coming fast in the center - I will book a hotel - see on next day the centrum and go fast back to the airport. Can you say me the best way? TAXI or AIR-PORT-EXPRESS or other BUS / SUBWAY ?What about working time? What about prices? THKS Daisy
