I will be travelling on the train from Shekou Port on line 2, She Kou lline.

Only Shekou Line cannot directly take you to the hotel, and the nearest subway station is Luohu Station, not Min Zhong xin.

You should take the following route.
Take the shekou line to Window of the World, and then transfer to Luobao Line to Luohu Station. Take the Exit D and walk about 680 yards, you will reach the hotel.
