During the pandemic, many hotels convert into isolation centres for the purpose of quarantine. However, the memorable experience in the context of quarantine hotel (quarantel) remains unexplored. Thus, the purpose of this research was to explore the memorable quarantel experiences of Chinese student returnees during the COVID-19 outbreak. The research was qualitative in nature, involving 26 in-depth interviews conducted through snowballing. The data was then analysed using thematic analysis. The findings revealed six themes - (1) staff, (2) room, (3) hygiene and disinfection, (4) food, (5) healthcare and (6) location - with 20 underlying attributes pertaining their experiences. Some themes (e.g. hygiene and disinfection and healthcare) and attributes (e.g. ventilation and Chinese food therapy) were found to be unique experiences with significant functions that newly added in the context of quarantine hotels. Besides, differences existed between operational guidelines of quarantine hotels and actual guests' quarantine experience. The research allows hotel operators to better understand guests' concerns during the quarantine period and offers managerial implications to improve hotels' performance during and after the pandemic.
