Every time I visit Hong Kong, I go to Tsim Sha Tsui to watch Hong Kong island from the other side as the light show starts at 20:00.
After the show, I head back to Hong Kong island with the ferry, which costs only $0.25 a trip. By the way, the bus only costs $0.4 to go from one side of the island to the other side. The metro costs $0.7 to do the same. That's free market economics.
