Don't try this at home

Lonely Planet this week celebrates its 30th anniversary. Along with Rough Guides and many other travel publishers, it has guided millions of travellers around the planet. Mostly, this is a good thing, from the host community's point of view as well as the tourist's. A good guidebook should ensure a traveller is informed about the nation's history, culture and social norms. They will get lost less frequently, get into less trouble, and enjoy the experience more. But some of the advice published in the past three decades may have led the traveller off the straight and narrow.
