Firstly I'd like to warn anyone booking this tour, leave plenty of time to find the place where you board the tram, the address that is given to you is an hotel and is not the exact place to board the tram. It took nearly a hour of searching and asking people around the address that we had been given, we even went into the hotel with the address given to us by Viator as the pick up point, and they did not know were to catch the tram. Eventually after running around for nearly an hour, we found someone who knew the exact pick up point, we nearly missed it, and it was the last tram of the night, we only caught it with a minute to spare. This was our first trip booked through Viator, we would not book another trip with Viator because of all the hassel we had with this one.
Oh this is fun. Our one hour tour on the top deck of a historical tram was brilliant. Recorded information about the route and sights is given via provided earpieces and in various languages. During the tour you are also given a pass that enables you to use any tram for the rest of the day and the following two days. We used them extensively and felt a part of Hong Kong life. This is leisurely travel so don't use if you are in a hurry !
Good trip, but there needs to be some signs or more detailed information as to where exactly the trip starts as Causeway Bay is not sufficient information if you are a stranger to the area. We missed the tram but a very kindly tram inspector took us to meet it further gown the track.
