UPDATE:
The book turned out to be decent background reading, but nothing one would take as a first choice everywhere. Many restaurant recommendations were good, some not so. But to be fair, the opinions were honest. And I am not sure what else I would take for a trip to Thailand. Its not a very difficult country to navigate with English spoken well and everywhere. Warning though on the prices, they were most inaccurate.
ORIGINAL:
We've been to Thailand before and covered a fair amount of the country. So purchasing the updated edition we were expecting to see a lot of the highlights of our previous visit, covered extensively. In this regard, Lonely Planet was a mixed bag. Some of the highlights from our visit to southern Thailand including details in and around Krabi were just not there. Also, visitors tend to use guidebooks and lean upon them for detailed recommendations of hotels. This book sets up brief and basic introductions, hoping instead that you use the internet instead to follow up on more details. Same for restaurants. If this was the true intention, websites and internet links would have been most helpful.
Its obvious that the book is not a complete overhaul from the pervious editions. A lot of the material is identical, word for word. Details of new hotels, ferry schedules, or the new low cost airlines flying internally in Thailand or within S.E. Asia are just not mentioned.
Still, its a reasonably exhaustive first step towards getting to know Thailand. And helping you plan your itinerary. Be warned though that you'll still want to use the internet a lot, to complement the information here.
Finally, I was contempleting getting the Lonely Planet Thailand's Beaches (including Bangkok) but that's not been updated at all in a long time (I intend to primarily spend time in the southern coast) and this book would be fine for most people especially if you are not anticipating the northern areas like Chiang Mai. Because this full LP version is rather heavy... and you are likely to not carry it with you everywhere you go. Still, overall-- a 4 star effort.
We are off to Thailand in August 2006. Stay tuned for updates to this review, the following month...
