The study have identified different segments of tourists visiting Tremiti by means of the model proposed by Arnegger et al. (2010), using the matrix suggested in the model. The model was used to understand and categorize visitor characteristics, their expectations and levels of satisfaction, and the strengths and weaknesses of local offerings. This is crucial information for the managers of the marine reserve who require thorough knowledge of the different types of visitors to adapt to the needs, expectations and preferences of the visitors in order to offer high-quality services and memorable experiences.
