In the above picture we are looking back the other way towards Salisbury Road and it's quite interesting to see (if you can just make it out) the old signal tower on Blackhead Point (top right). The grey building beyond the van is the Mariner Club along Middle Road. Suffice to say the open sky at the back is now filled with high-rises.
The two shots above are snipped from Episode 2, but we also return to the hotel during Episode 3 when Dunross goes to meet Brian Kwok, only to find out he is 'indisposed'. So in Epsiode 3 we also get a brief look inside the hotel lobby. From what I can remember of the place it hasn't changed much.
