Therefore, this paper aims to analyze customer satisfaction in luxury hotels using online reviews. Since Europe is a mature tourism and hospitality market, this paper conducts a comparative survey of luxury hotels in the top 10 European tourist cities by collecting customer reviews from TripAdvisor. This paper employs the Multicriteria Satisfaction Analysis (MUSA) model, a linear programming tool for customer satisfaction analysis, along with the refined Kano model to identify and compare areas for improvement in luxury hotels across various cities. The findings are presented through an interactive visualization application featuring a novel category-priority diagram to simplify comparison of criteria priorities. This application also provides automatic interpretations of the diagram for each city, allowing decision-makers to compare hotel performance, receive data-driven recommendations, and ensure analysis reproducibility.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/journal articlehttps://www.sciencedirect.com/science/article/pii/S0278431925003706open access311338.48640.41Customer satisfaction analysisComparative surveyKano modelMulticriteria satisfaction analysisLuxury hotelDecision-makingEstadísticaTurismo1209 Estadística5312.90 Economía Sectorial: Turismo
