This book is everything it's cracked up to be. One thing anyone considering buying this should note, though is that it's a UK based publication. In discussions about visas and work permits, it assumes EU citizenship. A lot of the advice wouldn't pertain to a U.S. citizen. Most of the directory information only lists U.K. based organizations.
That said, this is a great resource and very inspirational. It's made me think about going to places that I would have never even considered before. That's mostly because it combines engaging narratives by obviously well-travelled writers along with nuts and bolts practical information on the "how to" planning stages, and insightful advice.
It prepares you for the cultural differences you're likely to encounter, and prompts you to think about contingencies due to weather, medical, or political trouble. There are warnings about the hazards and adversity of some travel without trying to scare you away from it. The book manages to be a general purpose travel guide without being generic. It would be an equally good read for adventure travellers as it would for cruise ship enthusiasts.
The reference section alone is well worth the price, giving you fascinating and comprehensive information about every country on the planet. This book approaches you like a good friend who happens to be an experienced travel agent, hoping to help you plan a trip of a lifetime. It is remarkably well written and organized. I can't imagine planning a trip overseas without it.
