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.
[旅遊很大程度上是要逃避，而真正的旅行是要到達]

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".
