I purchased this book before leaving for 7 month backpacking journey in South America, from Chile to Colombia. I was a bit leery of checking out a relatively unknown publisher. Usually I stick with Frommers. Well in this case the weight of books was a big deal. I needed one book that had it all. Kindle based approach was less secure. Frommers guide to South America was full of expensive and mid-level places. I did't need a book to tell me that Hilton or Monasterio were good places to stay. But I needed a book to tell me where I could find a $15 hotel on a short notice.
Having a Footprint on the road was absolutely indispensable. Losing this book was tantamount to losing a passport or a credit card. In fact losing a passport would have been better because nobody in South America sold this book. I also relied on HostelWorld to book hostels but only because I hesitated in arriving into an unknown city without a booking. Once in a city, it was very easy to look up a place in a Footprint and book it on the spot. Having maps for just about any listed city or town was immensely helpful. Overall, this book was excellent for everything: top attractions for each country, restaurants in all price levels, hotels in all price levels with well represented budget tier, logistics like bus schedules and bus trip times, travel agencies and approximate tour prices. I highly recommend Footprint Guide to South America.
