It's not that this book is so bad, it's simply that it isn't worth the superlatives heaped on it by the other reviewers.
Although it is nice enough, it simply wasn't practical for bare-knuckle travelling. Having left behind the much more detailed (and therefore more informative) Bradt guides for Uganda, Ethiopia and Zanzibar (yeah, shame on me for being such a fool), I purchased this last minute substitute in an airport enroute.
It was a pleasant read, but not very helpful in trying to determined the easiest, cheapest or most enjoyable mode of transport from point A to point B - whether that was from town to town, or from airport to sleeping accomodations.
Some of the information was dreastically out-of-date (though that can happen with any guidebook that is not current) and the price informaiton was annoying. I much prefer seeing the prices next to the listing rather than go searching for some cost index table to decode each country's living expenses.
The thing I found most objectionable were the difficult-to-manuever maps.
The Bradt guides get my thumbs up recommendation. I am not a fan of Lonely Plant, but I have to concede that even their guide is superior to this book in terms of a practical travel aid.
