what is the quickest way to get from Hilton Hotel (Zhongshan) to Macau?

Take a taxi from the hotel to local main railway station (15min) and take a high speed train to Zhuhai (30-40min). After getting to Zhuhai Station, you may walk to Gongbei Border and cross the immigration. Then you will be at the Barrier Gate of Macau. Transfer to local transportation to your destination thereafter.
