 Here's the problem. Suppose you've come from a long way away. You're coming to Europe. You've got two weeks. You've spent ages saving up this money for this trip of a lifetime. You're there for two weeks. You come to Europe. You've got Schengen Visa, maybe. Of course you're going to go to the Eiffel Tower. Of course you want to see the Leaning Tower of Pisa. Of course you want to see Venice. And who are we to stop them?
