The concept of tourism is comprehensive and manifold, but it is certainly a real and influential phenomenon of the 21st century or modern society. Every day, millions of people travel or plan trips that become more complex with the company's development, and the complexity of travel is also influenced by the large offer or catering opportunities and the different demands of tourists. The definition of tourism by UNWTO is that tourism involves activities resulting from travel and stay of persons outside their usual environment for longer than one year for rest, business travel and other reasons unrelated to activities for which they receive any compensation in the place they are visiting. To make travel unmatched for both sides, ie for caterers and travelers, travelers need to know their rights and obligations before, during and after travel.
