I bought this book as I'm usually so happy with the lonely planet guide books and they've guided me around many countries but this one is just ridiculously out of date.
For example, it says that the East coast is still under strict guard with road blocks but this is not the case. When I showed that to the locals they were actually really upset as they're trying to make their country foreigner-friendly after a difficult time and this guide book doesn't help to get travellers to the East where money is very welcome after the Tsunami and fighting.
Despite saying it is printed recently the hotel I was staying at phoned their Asian office and they admitted they hadn't re-researched the existing information and had simply printed it again under a new date which I think it pretty awful!
Also, the map in the front is very inaccurate with some islands (for example pigeon island) being in completely the wrong place.
It's a beautiful, safe country and the people are so friendly. I would reccommend buying any other guide book and going off on a great holiday!
