The hotel is very close to the Huanggang Customs Port between Shenzhen and Hong Kong. The HK airport has frequent busese to Shenzhen via Huanggang Customs. You could catch one of them and get off at Huanggang Port. Exit from the customs, you could hire a taxi to the hotel direct at a flag-down rate. Or, you could get off at the bus's terminal at Shangri-La Hotel which is also not far from your hotel.
