The aim of the study is to identify the sustainability attributes of hotels preferred by guests and to compare the preferences of Hungarian and Tunisian hotel guests highlighting the similarities and differences. We used Q method to show which of the hotels’ sustainability practices and attributes identified in the literature are the ones that are preferred by the guests. There were two samples: 15 Hungarian and 15 Tunisian guests. Three group of opinions were formed in both cases. The essential attributes are those that have emerged as a common point in both countries' opinion groups. The elements related to the social sustainability pillar play just a small important role among sustainability practices. It is important for a sustainable hotel not only to be environmentally responsible, but also to be holistically sustainable, so it is worth incorporating social considerations, if not as an essential element. For sustainable thinking hotels, it is worth addressing the issue of sustainability and responsibility at a strategic level.
