Addressing the Attitude Behaviour Perception Gap—Multimethod Sustainable Tourist Behaviour Evaluation

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Quantitative and perceptual studies have been used to define and model sustainable tourist behaviour in past years, but few studies have undertaken qualitative research of actual behaviour to delve deeper into understanding the different classifications of such behaviour. This research employed a three‐phase design, comprising a pretrip survey,
