Every summer, Peter and Mary will bring their son and daughter for a short trip (at least 5 days) in an Asian city for them to experience different local cultures. This year, they plan to visit Hong Kong (which they haven't visited before), and would like to plan out some meaningful activities for their family, and look for useful advices on how to plan their coming trip.
The design solution is expected to enable/assist Peter and his family in designing a plan suitable for their needs.
