The subject of this special research topic is the analysis of the structure and function of the hotel accommodations of the sea shore in Greece, giving great attention to the procedure of their classification through the stars system, as well as to the size of the hotel businesses that are found in the Greek reality, and also to the online reservation systems, that are now the main way of communication between the customer and the accommodation. However, in order to be able to do that kind of research, what is firstly needed is the understanding of the concept of tourism in general, as well as that of the tourist, and moreover, of the evolution of the “domestication” of the sea shore through time, a procedure that was determined both by the tourist and the local population. The main goal is to target those elements that are assumed as deeply established in the field of tourism, and contribute in the unchangeable state that describes it the last decades. In order to have an improvement and an evolution in the phenomenon of tourism, it is necessary to question those data that are deeply inside its structure. The hotel, the landscape, the authenticity, the sustainability and the luxury will be the main keystones of this research topic, as they are thought to be the determinant factors of evaluation for both the seaside hotel accommodation, and the phenomenon of seaside tourism in general.
