Query: love the photos but it needs more maps

On a 10-day driving trip around mainland Greece this guide proved a disappointment. There aren't enough city maps so you need to buy a Lonely Planet guide as well. I love the DK guides to London and Paris where the neighborhoods and sights are so intricate that the DK diagrams and walking tours are immensely helpful. The restaurant recommendations turned out to be rather poor from the DK guide. Frommer's and Lonely Planet were a lot more reliable.If you want a guide that will help you sort out what's worth seeing, try the Michelin Neos instead.
