In planning a trip to Great Britain, I have purchased three travel books: Lonely Planet, Eyewitness and Frommer's. I would rank them in that order as far as helpfulness in planning our trip. Here are my reasons: I have found Lonely Planet's sections on "where to sleep" and "where to eat" are much more extensive, informative and include a wider variety in price ranges than the other two books. Also, they have more information on some of the smaller towns, that are off the beaten track. I enjoyed the wonderful photographs, maps and illustrations in the Eyewitness Guide to Great Britain and if you can afford two books, it is a great way to prepare for what you will see. However, since I only have room for one travel book in my small suitcase, I plan to take the Lonely Planet book with me on our upcoming trip.
