how to go to Victoria Peak form L' Hotel Nina, Hong Kong?

Do you refer to the L'Hotel Nina et Convention Center?
If yes, take West Rail Line at Tsuen Wan West Station, and get off at Nam Cheong Station. Then transfer to Tung Chung Line to Hong Kong Station. After arriving, walk to the Peak Tram Lower Terminus on Garden Road. Then you can buy the ticket and take the tram to the peak.
Have fun!
