By a nightmare of scheduling, I'm scheduled to arrive at HKG at 9pm on 8 Aug, and I have a departing flight from Guangzhou Baiyun scheduled to depart at 9am on 9 Aug. Is there any way to get there economically (or at all)? I can change the flight and arrive in Guangzhou, but it would be very expensive, and I already have paid for the Hong Kong flight and will get no refund, so I want to see if there is a cheaper way to get to Guangzhou overnight. Thanks in advance!
