I have booked my Hotel in Holiday Inn Golden Mile Kowloon, Hong Kong

The cab fare may be around HKD 240.

Or, you can take Airport Express line from HKIA to Kowloon Station (about 20 minutes). It costs HKD 90 per person. Then, take free shuttle bus line K3 to the hotel.

Or, you can take bus line A21 from HKIA to Middle Road, Nathan Road Station, and you can see it. The fare is HKD 33, and the trip takes about 70 minutes. :)
