I bought this book after trying to plan for some time a lengthy trip to Argentina, using a Rough Guide. I am far happier with this one! Printed on lightweight paper (after all, I'll be lugging it with me), but absolutely crammed with information, including the very helpful (and missing from many other books) logistics information about getting from a to b to j. All of these series vary in quality, depending on the particular authors - but this LP guide is excellent and up-to-date. Highly recommended.
