How do we get from Guangzhou (la Perle international hotel) to the Sharaton Cotai in Macau?

The best way is to take a taxi to Dongzhan Bus Passenger Transport Station for about CNY 20, and then take a coach to Zhuhai for CNY 65. The coaches are available from 6:55 to 21:00 at an interval of about 20 minutes.

Upon arrival at Zhuhai Gongbei Bus Station, walk south to Border Gate, and cross the border to Macao. Then, take a free shuttle bus of Sands Cotai Central to the hotel. :)
