This was exactly what I'd hoped it would be - I've been travelling about once a year for almost 10 years now, I've already been to all of the places on my list where travel is fairly easy, so I was looking for guidance regarding which hard-to-get-to places are worth making an effort for, and also hoping to find some interesting but easy-to-get-to places I hadn't thought of yet.
There are some nice pictures but this is not a coffee table book, it's a practical travel guide - I particularly liked that it tells you when is the best time to visit each destination, which is very handy if you like to make (rough) plans years in advance.
Since this is a book for people who actually plan to travel, countries that get more tourist-nights get more pages (which I liked), and some attractions that are currently not safe to visit are excluded (which I didn't like - this is a book to help you put together a bucket list to be ticked off over decades, and things could be very different 20 years from now: 20 years ago, who could've imagined feeling completely safe in Cambodia but in danger in France!).
I first came across this book in a (physical) bookshop years ago but didn't buy it because I thought the $40 price tag was ridiculous, but since it's a bit old now I managed to get it on sale online for half that, but I think even that's a bit steep since this is basically an ad for Lonely Planet's other books - there's not enough information here to plan independent travel, so you'll need to buy another guidebook for each place you actually decide to go (or do lots and lots of online research, but if you were willing to do that you wouldn't be considering buying this book!). For that reason, don't be afraid to buy the old edition if a newer one comes out.
