Hi I stay in Kowloon crown plaza. Which is nearest place to see symphony of lights?

You must refer to Crowne Plaza Kowloon East, right?
The distances from several best sightseeing places to the hotel don't have large difference. So it's suggested to go to Avenue of Stars to see the light show.

As for the transportation, take Tsueng Kwan O Line, and get to North Point Station. Then take Island Line to Admiralty Station and transfer to Tsuen Wan Line to Tsim Sha Tsui Station, Exit F.
It takes about 40 minutes. And the ticket fare is 9.4 HKD per adult.
After that, walk south around 440 yards and arrive at the destination. This place is one of the best sightseeing stand. :-)
