Took this with us for a week in Sorrento and it proved to be very useful. A decent mix of practical information (how to get places, recommended eating places etc.) and guidebook, it gives a good background to the area, and as the title implies focuses on family friendly aspects rather than the latest trendy bars.
Minor annoyances are the 'kids will love' comments that litter the book - not all kids like the same thing - and on one or two occasions directions weren't clear.
Overall though definitely worth your while if you are traveling to that part of the world - and I'd certainly recommend that you do.
We took this guide book on our recent holiday to Italy with our two children, aged 10 and 12. I bought it in the hope that it would give us a different angle on some of the places we planned to visit, but felt that in reality it did not point you towards child-friendly activities (other than beaches etc which we all know about). Actually, it seemed more designed to assuage the guilt which parents might feel doing normal adult stuff by promising them that "children will love it". Does anyone really think that a long drive along a road with hairpin bends and a nice view (the Amalfi drive) would classify as the number one children's favourite activity in the area, or that it would provoke "whoops of exhilaration" from the back seat? Or that children would get excited by the prospect of looking at a fountain? Get real! On top of this, the book provides insufficient detail about the sites it describes, and is written in an extremely annoying, gushing tone. Get a mainstream guide book like Lonely Planet instead - it will be much more use!
