I've traveled all over the world, and years ago I considered Lonely Planet the very best for those traveling "off the beaten path." I'm sorry to say that this book is the worst LP book I've ever read. The information it gives is no better than reading a web site: no personalized details, no invaluable advice, no descriptions that would help you choose one hotel over another, one attraction over another, etc.
I'm going to Chile and Easter Island in three weeks and I've gotten very little helpful information from this guide. For example: I want to know the best way to see Easter Island... car, horse, foot, bike, or motorbike. This book simply states that these are the ways to explore Easter Island, but doesn't recommend which might be better for whomever for whatever reasons. The most it does is to say that if you rent a bike, be prepared for some steep hills and twisty roads. Another example: I want to take buses from Santiago to a couple of different places. The book just gives a confusing list of bus stations and the bus companies, with some examples of where they go, but makes no recommendations on which is best to use. This is information I can get from a brochure. I was also trying to find out a way to get a less expensive fare to Easter Island. In the old days, I could count on an LP guide to tell me the best and absolutely cheapest way to travel. This book just lists LAN with its web site info. I found better advice going to the LP forums. I also found better hotel info on Booking.com.
In my opinion, the value of a good travel guide is personal recommendations from people who have traveled to the place, particularly those traveling off the beaten path. In the old days, LP guides gave really great advice, personalized recommendations, on the best places to stay, out-of-the-way places to eat and visit. This is the first LP book I've bought in about 15 years. I hope they're all not like this now.
