Data aggregation 
In order to check the effect of the multilevel structure of the dataset, in which persons were nested within 
hotels, a variance components analysis was run using MLwiN 2.0 software. For perceived customer satisfaction, the 
analysis showed that 16.67% of variance was represented at the hotel level (i.e., ICC = .1667). Conversely, 83.33% 
of the variance was represented at the person level (i.e., ICC= .8333). These values are well within generally 
accepted ICC values from the relevant literature (Dietz, Pugh, & Wiley, 2004; Liao & Chuang, 2004). It was 
therefore concluded that the aggregation of data was justified and the original data was used for the present research.
