This report analyses the determinants of the length of stay of international tourists taking vacations in Mauritius, based on a questionnaire distributed in the departure lounge of the Sir Seewoosagur Ramgoolam International Airport. A survival model was adopted to measure the relationship between duration of stay and the different covariates. It was concluded that the length of stay at the destination is related to the various demographic characteristics, rating of trip attributes, sustainability practices and personality traits of the respondents. Thus the need for taking into consideration these factors for marketing purposes and eventually the sustainability of tourism industry in Mauritius is being advocated for.
