There are many practical problems that we must come to grips with in our daily lives. Often, we are presented with options or alternatives in reference to these problems. How we weigh and choose which course of action to pursue is of obvious significance. We may choose rationally, i.e. we may choose the option that is judged to be in our best interest, or we may choose irrationally, i.e. against our better judgement. In the latter case, we would be succumbing to akrasia -demonstrating weakness of will, where the search for pleasure overwhelms good judgement. This paper applies the concept of akrasia to two tourism case studies: one, on the choice to purchase endangered animal souvenirs in Cuba, and the other on sex tourism in Costa Rica. I conclude by suggesting that codes of ethics, accreditation schemes, guidebooks and interpretive programmes have a role to play in educating tourism actors on the importance of choosing alternatives that support broader initiatives over those of a strictly personal (i.e. self-interest) nature.
