“To be a tourist is to escape accountability.”

“I'd rather lie bare-assed naked on the sidewalk and be trampled by tourists from South Dakota than be an accountant.”

“Twoflower was a tourist, the first ever seen on the discworld. Tourist, Rincewind had decided, meant 'idiot'.”

“But some natives--most natives in the world--cannot go anywhere. They are too poor. They are too poor to go anywhere. They are too poor to escape the reality of their lives; and they are too poor to live properly in the place where they live, which is the very place you, the tourist, want to go--so when the natives see you, the tourist, they envy you, they envy your ability to leave your own banality and boredom, they enjoy your ability to turn their own banality and boredom into a source of pleasure for yourself.”

“Industrial tourism is a threat to the national parks. But the chief victims of the system are the motorized tourists. They are being robbed and robbing themselves. So long as they are unwilling to crawl out of their cars they will not discover the treasures of the national parks and will never escape the stress and turmoil of the urban-suburban complexes which they had hoped, presumably, to leave behind for a while.”

“Life is a journey so everyone is a tourist”
