Hi, Mr Tan:
1. By ferry: about 170RMB, about one hours
2. HK-Macay Ferry Terminal. The hotel should have shuttle bus to the terminal.
3. Take Bus K204 or 204 at Shekou city Bus Stop to Guomao and then take a taxi to the hotel. For you are are formaliar with the hotel location, it is better to bo by taxi directly. It needs 40 minutes from Shekou to the hotel by taxi. The taxi fare is expensive, not a economical way.
