I am travelling from USa to HKG airport February 12. supposed to arrive in Hong Kong at 20:25 (8:25pm). what is the best? easiest? fastest? cheapest way to get to Shenzhen Bay customs before 24:00? How many HKG dollars should i exchange for? Thank you so much. I am meeting my girlfriend there...and she is somewhat new there from Wuhan. Can you recommend anywhere to go?
