What can I do with an 8 hour layover? Arrive HKG at 23:30 and Depart at 7:00 the next morning. It's two CX flights. Will they let me transit or do I need to exit the airport? I have lounge access. Can I use the lounge before it closes that night? The hotel at the airport is about $200 and that's a bit expensive for about 5-6 hours rest.
