The point of departure of our analysis is that tourism is the encounter of two populations, a temporary as opposed to a permanent resident on a given territory (Bimonte 2006; Bimonte and Punzo 2006; Smith 1989). Their needs, interests and expectations not necessarily being either convergent or even just similar (Hardy et al. 2002), heterogeneity has to be taken into account as a fundamental analytical feature. Moreover, encounter in a given ‘destination’ implies an added demand to share local resources from the part of the visitors (in the language of biology, acting like invaders), and the residents’ territory has to ‘double up’ and perform an additional, or even a new principal role of, other people’s temporary home. Local resources have a record of locally historical usages (hence, basically, they are to be accounted as heritage goods), but at one point they have drifted into the sphere of interest of (mostly) leisure-motivated visitors.
