This lightweight guidebook made a useful companion on our visit to the Cinque Terre. For each of the five towns (plus some of the surrounding towns as well), it includes a brief description, a sketch map, a short walking tour, and recommendations for places to eat and stay.
Rick Steves is apparently a well-known travel writer and celebrity in the US. I would not be at all surprised if the mere mention of the Cinque Terre in his compendium guide to Italy (of which this book is an extract) is mainly responsible for the volume of American visitors to the area. Nearly all the Americans we encountered in the Cinque Terre had a copy of this book (or the equivalent pages ripped from the compendium). This means that the vast majority of tourists in the region tend to flock to the places recommended in this book, while equally good places right next door may be nearly empty.
That's really the biggest problem with this, and any other, guidebook; the recommendations are based on personal preference and may quickly get out of date. We found at least two really good places that the writer dismissed, and at least one place that the writer recommended that we thought was average at best. Fortunately, the Cinque Terre towns are compact enough to explore without risk of getting lost, and the walking tours made a very useful basis for this.
For a European reader, there are some occasional additional surprises in the author's choices of sights worth seeing. For example, he goes out of his way to discuss local planning laws, which do not seem to be any more strict than other historic European towns, yet which presumably have US citizens tutting at their severity. The author is also at pains to point out that American tourists sometimes have a bad reputation overseas, and offers some pointers towards being better travellers.
However, any such cultural differences, the occasional dodgy recommendation and even the information that is already out of date (such as the local train timetable) can easily be forgiven for this book's simple usefulness, and for a handful of really good, slightly wacky suggestions that we didn't see recommended anywhere else but which proved to be great fun.
