Tourism in the 21st century is being re-shaped by constant changes in consumer trends. The Danube, Europe’s second-longest river, has rich potential for tourism over its whole course, and river cruises offer superb opportunities to explore. This study aims to provide a comprehensive picture of the most important characteristics of cruise tourism on the Danube. In our research, a literature review (LR) and content analysis (CA) were used to examine trends in the inland waterway cruise sector, which, despite the growing interest in the product, is still not deemed to be a part of mass tourism. Danube cruise tourism relies heavily on alternative (niche) tourism features, which satisfy both cultural and authentic tourism preferences. Currently, many elements of niche tourism are missing from the product supply, but, with a modest addition of such features, the demand for the product could increase and its economic performance in the period following the expected recession would be enhanced.

The rapid emergence of automation brings new opportunities for airport development. Airports strive to maximize passenger satisfaction as well as optimize their operation. However, the lack of knowledge of consumer preferences might be an important barrier to achieve these objectives. Therefore, our study aims to unveil the potential of service development alternatives based on artificial intelligence (AI). For this, a systematic literature review (SLR) and a quantitative analysis of a survey have been conducted. The results of the empirical research are based on 593 responses; most of the subjects belong to generation Z (digital natives) and Y (millennials). The analysis revealed attitudes towards different AI-based transport solutions and AI robots that provide information at the airports. Based on the perceived attractiveness of such services, the environmentally conscious behaviour of consumers, and sociodemographic data, subjects were classified into three different clusters (Negligents, AV Enthusiasts, and Robot Fanatics). Results proved the attractiveness of AI-based transport services that can be used in the air-side zone. Among the millennials, the idea of self-driving buses running between airport terminals is the most appealing. Greater interest in AI-based communication solutions can be perceived among generation Z. For both generations, environmentally conscious consumption is also of paramount importance. The attractiveness of AI-based solutions has been analyzed in a tourist environment, which might be a good starting point for further research into the technology acceptance of AI-based services.
