When we have a tour, it is important to have good travel agencies, good tour guides, good places to go. But a lot of people neglect a point --- we ourselves should be qualified and good too. The memeber of the tour group should contribute to the success of a trip.
so next time, when you start to complain about a tour you join, consider again, maybe you are not playing a good part in it too.
