Communication is involved in all social life acts, being the constituent factor of creation and of cultural processes. Cultural diversity and intercultural dialogue are intensely discussed topics in today's society which is marked by globalization. Cultural differences are the core subject for studies addressing intercultural communication. Good knowledge of other cultures is a necessary step to get to recognize the nature of these differences and to relate to others through attitudes of understanding and tolerance which are premises for genuine intercultural dialogue, especially in the tourism industry. While communication is an act of human relationships, culture is the motive of this act. In tourism, quality of communication is related to the level of the culture involved and to the degree of improvement of the means of which is done. Intercultural communication experiences help tourists to know and to appreciate other cultures, but also help them to a better understanding of their own culture.
