Anyone who needs more than one suitcase is a tourist, not a traveler

A traveler enters the world into which he travels, but a tourist brings his own world with him and never sees the one he's in.

...a tourist can't help but have a distorted opinion of a place: he meets unrepresentative people, has unrepresentative experiences, and runs around imposing upon the place the fantastic mental pictures he had in his head when he got there.

Move to a new country and you quickly see that visiting a place as a tourist, and actually moving there for good, are two very different things.

Each member of this shadowy network resented the others, who were irritating reminders that nothing was more American, whatever that means, than fleeing the American, whatever that is, and that their soft version of self-imposed exile was just another of late empire's packaged tours.

The traveler was active; he went strenuously in search of people, of adventure, of experience. The tourist is passive; he expects interesting things to happen to him. He goes "sight-seeing."
