My family of three will arrive at Hong Kong Airport Tuesday night 8pm and fly out the next morning 8am. We'll have luggage with us (diving gear). What is a good option to get some sleep for the night without paying US$180-$220 (I checked all three hotels near the airport) for 8-hr sleep near the airport? Considering round trip fare on Airport Express is US$23 per person, I'd rather not spend the time and money to travel to the city and back to the airport in 8 hours. We'd like to be civil and not sleep in a public area ... Thanks!
