People tend to check in during these times:
Transfer spot for Far East car limo/car services from SZ to HK. Most of the drivers drive like race car drivers, but they just try to make up for time lost waiting in line at the border.
This is the drop off and pick up point for eternal east car service. One of my prefered car service from HKIA to Shenzhen
Cross-border service to HK airport available with major airlines pre-check-in. But for shopping you'd better choose not that far Holiday Plaza.
Check out CrushedGrapes Pop Up Store on UG floor! Great mid-autumn festival deals!
