The World Tourism Organization defines tourism consumption as the amount of funds paid for the acquisition and consumption of goods, services and values for one's own needs or as a gift to others in connection with a tourist trip. Technological innovations in tourism are: artificial intelligence, virtual and augmented reality, sustainable development and smart cities. Artificial intelligence in tourism is: online check-in, automated doors, restaurant with conveyor belts for serving food and drinks. Virtual technology is the use of technology that provides users with a virtual experience. Augmented reality is adding elements of the virtual environment to the reality in a way that makes it look realistic. Six prerequisites for successful implementation of the concept of sustainable development: strategic development planning, developed system for measuring and monitoring development, interrelationship of all stakeholders, stimulating institutional environment and proactive local government, engagement of local population and education, and awareness of local population. The concept of smart cities is an urban development that uses digital and communication technology and the Internet of Things. The application of the concept of smart cities in Croatia is achieved through smart urban local transport, smart digital urban infrastructure, involvement of citizens and the local economy, smart data and visualization, and smart leadership. The scientific hypothesis of modern technology and their implementation affect better tourism results and consumption has been confirmed.
