We are flying from Mumbai to n from San francisco with stopover @ Hongkong .

1. For 9 hours stopover: I suggest you go to Tsim Sha Tsui & Victoria Bay for sightseeing. The nearby area is also good for dining and shopping. If it is night, you can appreciate the Symphony of Lights.
2. For 14 hours stopover: You can make full use of time to go to Victoria Peak & Madame Tussauds. It is a must-see in HK. If preferably, Ngong Ping 360 is a good place to go and you won't be disappointed. Choose one between them!
