It is important that all participants in destination tourism offer understand the basic models that attempt to explain consumer behaviour. In fact, it is the responsibility of tourism professionals to identify target markets, attract them to their destination and satisfy them by providing quality and unforgettable experiences. It is, also, the responsibility of tourism professionals to develop marketing and management strategies based on accurate knowledge of tourism behaviour. Tourists have different motivations, expectations and behaviours, and vary in nationality, culture, social class, travel experience, etc. Therefore, tourism professionals need to review travel demand data and factors affecting international and national demand. All of the above is very important for understanding the structure of tourists' spending in a particular tourist destination, as well as to plan further development of existing and creation of new elements of the tourist offer in the destination.
