I will be in Hong Kong with my family on Dec 30 to Jan 2. Anyone please advice how does the tourist 3-day pass work. In my case, I will be there for four days but arrive late night on Friday and leave before noon on Monday, so I will be there virtually less than 72 hours. Can the pass be used for three individual days or based on 72 hours from first use?

Another query, please advice best place to be for count down. I will be staying at Novotel Hong Kong.- Many thanks in advance
