The opportunity to travel is precious. To go somewhere else- to see other people are doing, how look and how they are dressed, to hear what they are saying, and to be exposed to their culture - is a fantastic plus. For both the traveler and the people who live in the destination city or country, manners are key to successful interaction.
Any trip can be a success- if the people taking it will its success. That old cliché of having a positive attitude really works when you're traveling.
