Craig Storti:
Why Travel Matters(2018)

Tourism is largely escape from whereas true travel is arriving at; tourism is mainly recreational whereas travel is primarily educational; tourists are driven around and served by the locals whereas travelers want to meet them; tourists want to relax whereas travelers want to be stimulated; the goal of tourism is to see the sights, while the goal of travel is to add to understanding.

Paul Theroux, in his trademark curmudgeon mode, observed that "travelers don't know where they're going [because that's not the point] and tourists don't know where they've been". In The Oxford Book of Exploration Robin Hanbury-Tenison makes his own sharp distinctions: "There are tourists and there are travellers. The former go abroad to rest their bodies and their minds, no more. The latter go to see and understand".
