The broader mix of historical background, orientation and practical information is welcome. A good all round guide, though not as inventive as they market as being. Still, it is one of the best general purpose guides out there. Covers all of Western Europe as an`all in oneŽ guide.

Let's Go Europe is the best selling of all the euro guidebooks, covers all the main countries you're likely to visit and has been around for over 20 years. Often referred to as the bible of budget travel it's compiled by a group of some 30 Harvard students who collect details on a  tour of Europe the summer prior to publication. Its main strengths are the emphasis on value for money and nightlife. Follow the Let's Go 'bible' and you'll not be far from the party crowd, particularly the American party crowd, if for no other reason than everyone else is reading it too!
