Accommodation tourist industry is characterized by high variability. For this category of services not only the location is crucial- that does not change, but also the standard, prices and seasonality of services. In the recent years, leisure centers performing functions only during the summer time have seen the possibility to extend their activities beyond the summer months. The reasons for this are the local investments requiring qualified staff which comes from different parts of the country, Europe and the world while creating dernand for accommodations. To meet the possible demand needs and to adapt to cold season, performing thermo-modernization works is necessary. In order to find the best solution and answer those needs, analysis of the profitability of the investrnents in a chosen holiday resort was carried out. The article presents the results of the analysis based on the payback period, LCC analysis and assessment of the investments risk.
The ILC is an immense e+e- machine planned since 2004 by a large international collaboration, to be potentially built in Japan [1]. The gigantic size of the whole research infrastructure, the involved human, technical and financial resources, and the pressure of new emerging and potentially soon to be competitive accelerator technologies, make the final building decision quite difficult. A vivid debate is carried on this subject globally by involved accelerator research communities. The European voice is very strong and important in this debate, and has recently been essentially refreshed by clear statements in a few official documents [2]. The final HEP European Strategy Document is just under preparation. This paper is a very modest and subjective voice in this debate originating from Poland, which around 50 researchers are present at the list of 2400 signatories for the original ILC TDR document published in 2013 [3].
