This study aims to investigate the moderating variable of environmental practice on the relationship between service quality and customer experience in the hotel industry in Malaysia. The influence of service quality has been long known in the literature to have a profound effect on hotel guest experiences. Yet, this paper presented the result of a survey of 150 hotel guests that was recently carried out in four and five-star rated hotels in Malaysia. A variance based of structural equation modeling (PLS-SEM), a component-based structural equation modeling, using SmartPLS version 4, was used to estimate the interaction effect of the moderating variable of environmental practices on the link between the endogenous variable of service quality and the exogenous variable of customer experiences. A structural model was then put forward with its respective measurement models and the newly developed indicators. The result shows that environmental practices have a significant moderating effect at ρ < 0.05 suggesting positive indications to increase occupancy growth percentage. Practical implications were further discussed and hoteliers that have not done so ought to incorporate the importance of green practices.
