i would like to know,is there direct transport by road or rail way to reach from hongkong international port to macau?

As far as I know, only the ferries can be used for transporting between the two places.
The ferry takes about 50 to 60 minutes to reach M from Skypier of HKIA.
I think Ole London Hotel is a nice one with reasonable price.
For the places to visit, the A-Ma temple, the Macau Tower, Ruins of St Paul, Senado Square, Avenida de Almeida Ribeiro, the Venetian, the City of Dream, the Fisherman Wharf and the Forte are suggested to go.
