D1, take Tung Chung MTR Line and change to Disney Resort Line at Sunny Bay Station.
D2, take Tung Chung MTR Line to Laiking and change to Tswen Wan Line, alight at Admiralty Station and take Bus 629 to Ocean Park, to the peak, take bus 629 back to Admiralty and take bus 15 to the peak, or you can also take tram there.
D3, take Bus 23 to Ngong Ping or take Ngong Ping 360 cable car to Ngong Ping.
I suggest you go to avenue of stars and watch the Symphony of Lihgts show, if possible. For Night Market, you can go there after visiting the Peak, you can take tramway or bus down the hill and then take Tswen Wan MTR Line and alight at Jordan Station and then walk to Temple Street Night Bazzar.

Thanks a lot Mr.HONGKONGMAN for the quick response. Just want to know how to get to the avenue of stars to watch the Symphony of Lights show. Which area of our iterinary would it be near to go there? Also, how are we going to go back to Novotel Citygate Tung Chung from the Avenue of stars and the Temple Street Night Bazaar? Can you recommend any modification of our plan/route to make it more time consuming for us to maximize our stay in Hongkong? I appreciate much any insight you can give to make our vacation more memorable and less confusing.

You can put Avenue of Stars in your Day2 plan, after visiting the Peak, you can take the tramway or Bus 1 down the hill, walk to Star Ferry Terminal and take Star Ferry to Tsim Sha Tsui, there you need to walk to Avenue of Stars and enjoy the Symphony of Lights, after the show, you can take Subway Line Tswen Wan and alight at Jordan station and walk to Temple Street Night Bazzar. After visiting the night market, take Subway Line Tswen Wan to Lai King and change to Tung Chung Line, alight at the Terminal and walk to your hotel.

A million thanks Mr. Hongkongman! You're a great relief to my anxiety of planning this trip. Have a great day...
