The OP was asking about arrivals facilities , not transit facilities. Transit hotels are only available to transit passengers. At HKG the Regal is not a transit hotel as it is landside so can be used if HK is your final destination, or you are prepared to exit the airport on a layover. In my case which I refer to above I was not transitting, rather transferring to the China Ferry, which is downtown, not one of the airport ferries.
