Arrival at Hong Kong Airport very late at night, does airport bus still run?

Hi, i'm going to HK in may. I booked Regal riverside hotel at shatin. But my arrival time in HK airport is 22:45 (HK time), very late at night. Before i can leave the airport (after checking out, taking luggage..), it will take at least 30 mins minimum i think. The time will be around 23:30 or sth like that, so can i still have airport bus available at this time? I know the last bus is 24:00, but I can't be sure if it's really the last one to depart the airport. please help, thanks!
