The Italian tourist sector is historically affected by seasonal problems: in many locations the tourist season lasts only for 4-5 months per year. For the remaining 7-8 months hotels and leisure activities are forced to close: in these months of low season expenses could be higher than revenues. Italian seaside tourist areas are the most affected by seasonal adjustments: even for this reason return on investment could not be so attractive for the main international brands. During the last years some operators tried to get round this matter diversifying the offer: SPA, wellness centres, business centres, etc.These devices are only local and segmented operation that do not lead to a resolution of the problem. The aim of this study is try to identify some categories till now ignored by the tourism sector and demonstrate that invest in these groups of people could help the renewal of the sector. Each category will be analysed in order to individuate the qualitative and quantitative aspects that can impact on the tourism sector: - demography: quantification and trends; - purchasing power; - propensity to travel; - the way of life; - etc. // For each analysed category we will estimate the increase of the number of travellers and the impact on the turnover of the Italian tourist sector that is possible to gain investing in these groups.
