Why travel? For tourism scholars, this has been a question that has enlivened, haunted, and otherwise driven our desire to understand human mobility and the travel and tourism phenomenon. Why do people travel? Why do not they just stay home? A good portion of the sustainability challenges that the world faces today could be avoided if everyone would just stay home (Houser, 2017; Miles, 2017). There would be no 'overtourism', there would be no (or less) airplane and cruise ship induced climate change, and there would be less placelessness and more of a sense of place in communities worldwide (Tourtellot, 2017). I am, of course, speculating on these things because it is hard to imagine what the world would be like if there was no leisure-based travel and tourism. All we can say is that it would be a different world. We do not know if it would be a better world. The benefits of the travel experience have long been a part of the cultural iconography of the western world. Mark Twain (1869b) famously wrote in The Innocents Abroad, Travel is fatal to prejudice, bigotry, and narrow-mindedness, and many of our people need it sorely on these accounts. Broad, wholesome, charitable views of men [sic] and things cannot be acquired by vegetation in one little corner of the earth all one's lifetime.
