The purpose of the thesis is to clarify and investigate the complexity and usefulness of business guest satisfaction in the hotel industry of the Republic of Croatia. Every day, many hotel companies encounter unexpected, dynamic, and profound developments in the international market. Guests want complete service and good value. Existing hotels must invest in quality improvement to meet the needs and expectations of their users. With the increase in the number of hotel services and the overall increase in competition in that area, it is essential to focus on the needs and wishes of business guests to retain them so that the service itself can progress. Business guests are an important group of guests who require certain conditions in the accommodation facility, and these conditions must be clarified for the hotel industry to adapt and improve, which is what the research was for. In the research work, which was conducted on a total of 102 respondents in the period from June to September 2022, the task was to define the level of satisfaction of business guests with the hotel services that are currently offered. As a research instrument, a survey questionnaire distributed in physical form was used at the check-out at the reception, and the sample deliberate. The results clearly show and confirm past research, which states that business guests are generally less satisfied with services and that they should be given more time and attention and use an individual approach. In this way, it is possible to achieve better business results and enable a more adequate offer to the specified target group.
