whats the best itinerary if your staying in emperor hotel in happy valley, HK.kindly give us instructions on what places to go first

Walk from your hotel to Happy Valley Terminus to take the local tram Kennedy Town - Happy Valley Line and get off at Des Voeux Road Central (Bank Street), from which walk to Garden Road to take the peak tram to Victoria Peak. After that, get down by the tram to Central, where take subway Tsuen Wan line to Tsim Sha Tsui Station and walk to Avuenue of Stars to enjoy yourself. Then the Symphony of Lights can be reached by walking from the Avenue. Afterwards, take Tsuen Wan line to Mong Kok Station and walk to Temple Street Night Market to have a joy.

I don't think time is enough to go shopping at Causeway Bay on the same day. Anyway, if you wish, the Tsuen Wan line will take you to Admiralty, where transfer to Island Line to Causeway Bay then.
