I've always liked Lonely Planet travel guides...I feel like they provide a lot of "off the path" points of interest that other books simply pass by. However, the last few years I've been using the Eyewitness guides and I'm starting to prefer them to the Lonely Planet books. I feel like the Eyewitness books have a lot more to offer in the visual sense, with their color pictures, maps, and walking tour suggestions. Lonely Planet has good info, but the format is just too textbook for my liking.
