Neon lights and lots of people
Hong Kong is very lively city and always open way past midnight. There's people everywhere but also much to see.
Insider Tip:Buy octopus card from the subway station help desk. It's easy to use and very cheap way to explore the city. Octopus card holders use the GREEN entrance and exit gates! Just place the card to the card reader area on top of the gate entrance desk. If you like to have some more space inside the subway cart walk to the farthest waiting areas on either side of the subway platform.
