Good fun and educational my daughter loves playing with us and sorting it on her own. There are a lot of small squares which could be easily lost but with supervision it's fine and it clearly states how many bits there should be so that you can count them back in.
I found this a great help for planning our holiday abroad. It recommends things and places to go right up until their teens and covers the world. I will definitely be using this book for insipiration for all future family holidays.
