I have recently completed a 12-month backpacking journey around the world, a trip that included Laos. In each of the 20-some countries I visited, the Lonely Planet I carried proved invaluable. However, after having read some of the other Amazon reviews of the LP Laos book before using it, I was expecting this particular guide-book to be worthless. But in fact, after using Cummings' book for nearly a month in Laos, I was pleasantly surprised to find it as useful as any other LP that I have used. Actually, expecting this guide-book to be useless, I brought along another Laos guide-book, which proved to be much less useful on the road when used side-by-side with the LP.
Not only did I find the accomodation and eating sections for popular locations as accurate and update as I would expect, but Cummings' did a fine job of briefly describing many off-the-beaten-track places, providing initial ideas for numerous adventures into the unknown.
And of course, as in any country to see the "real-thing", it is always rewarding to venture to places that you have not read about in a guide book. For this reason, I would certainly not criticize Cummings for not writing more.
All in all, in my opinion this book certainly meets the lofty standards set by Lonely Planet.
A bit of advice to would-be travelers: During my 12 months of diligently using Lonely Planet guides, I have been amazed by the travel-blunders made by fellow travelers who have carried travel guides, but have not used them. Some travelers perfer to do it "on their own", but I have seen numerous costly, time-consuming, and uncomfortable mistakes made that could have been easily avoided if they would have simply consulted the book in their hands. A little diligence goes a long ways.
