I've used several travel-related Rough Guides and have generally been pleased. They're well researched and written. They state opinions about things, and I've found that I usually agree with theirs. One aspect I don't like, however, is their use of letter codes ("A", "B", "C", "D", etc.) with an associated key to indicate lodging price ranges, instead of simply giving the actual dollar amounts like other guidebooks. Lonely Planet guidebooks for countries or regions tend to contain information for some more obscure places which Rough Guides omit. Rough guidebooks for cities tend to be excellent, however.
