Since the dorsett seaview hotel is near to Yau Ma Tei metro station, you can take MTR from Yau Ma Tei to Central, then take bus 1 to the peak. Walk along the peak road, you will see the madame tussauds. When go to the Golden Buddha, you can take MTR Kwun Tong line from Yau Ma Tei to Wong Tai Sin, then catch a taxi to the buddha.
There seems no hotel shuttle from Metropole hotel to yhe ferry terminal. Since the two places are not far from each other, you can take a taxi from the hotel to the ferry terminal.
