Pre holiday -- As about to go on holiday to this area we wanted to know all the best places to visit apart from the obvious like Pompeii and Vesuvius. We have also discovered the easy ways to go to Herculaneum and Ischia apart from many others. Will be taking this book with us as a guide to what and how to visit when there, but it is great to read up before hand just to have a bit of overall knowledge . Post holiday -- Having just come back from the Naples area we found this book invaluable. How and where to buy bus tickets, journeys on the train and funicular, opening times of castles etc. In fact there was so much info in this book I cannot give it justice in my review except to say buy a copy and refer to it for whatever your needs.
