The nationality of guests staying at the hotel at any given day was accessible through the hoteldatabase. Note that this information was not available at the level of the guest, so it was not possible to identify individual guests, only the mix of nationalities per day was available. Nationalities included Austrian, Slovenian, Italian, German, Hungarian, Belgian, Slovakian, Russian, Czech, and other. This information allows determining for each day the proportion of guests from the different nationalities, that is, the proportion of Slovenians among all guests staying in the hotel on a given day.
