The easy way is that you could take a cab drive you 5 people to Luohu Port from the hotel directly. The fare is no less than 300HK$. Go throught the customs port, you could take two taxis to the metropark hotel at flag-down rate.

For saving money, please hire a taxi taking you from Largos to Hung Hom. Here, you could take the KCR East Rail to reach Luohu with a fare of 33HK$/per person. Others are the same!
