An extensive literature of Choice Experiments (CE) has recognized that it is usual, especially where there are many attributes, for a person to ignore one or more attributes in the alternatives presented on the CE choice cards for many reasons. Yet, there is evidence that persons who declared they have neglected or ignored certain attributes might actually have given them lesser or lower importance. Stemming from this evidence and given the significant implication of not accounting for attribute non-attendance (ANA) in welfare estimates, we apply a supplement question in ANA to investigate how respondents pay attention to the attributes. Different techniques for modelling ANA in a case study investigating preferences of the visitors for the tourist facilities attributes in Malaysia are then compared. A conditional logit (CL) models analysis reveals different willingness-to-pay (WTP) estimates after accounting for ANA, suggesting the importance of considering ANA in the analysis and considering the appropriate method to deal with it. The results also reveal that different categories of visitors influenced the exclusion of a specific attribute. This information provides hints to the policy maker in understanding potentially conflicting preferences between different types of visitors which is useful for the sustainability of the tourism sector in the future.
