The implementation and success of hotel management depends mostly on physical characteristics such as people (visitors) and accommodation (facilities). However, as technology evolves, and becomes an important component in the development of industries, it is more present than ever in the hotel industry. This paper explores the connection between informatics, digital technologies and hospitality, on the example of the hotel group Plava Laguna d.d. Field research was conducted from May 28th to June to August 10th.2021, and the results were obtained using interview, analysis and deduction methods. The aim of the research was to get acquainted with the used digital technologies and information and communication technologies (with emphasis on the new ERP system) in the company. The purpose of the research was to show solutions in practice according to technological innovations from the management. Since the results were obtained from one hotel facility, it is proposed to conduct similar research in other facilities in order to get a more accurate situation assessment. In addition to research, this paper includes a deeper analysis into business processes, ERP systems, digital technologies and hospitality/hotel management.
