This review compares the Lonely Plantet Greece (4th Edition) with the Rough Guide Greece (8th edition). We spent 2.5 weeks in July, 2001 in Greece, our first visit, and these were our guide books.
A relucant 4 stars to each, and a slight preference for RG. We certainly found the books serviceable, and they gave us good ideas of where in Greece we wanted to go. But they were much less valuable in their listings for individual destinations. They were the least valuable compared to the other LP and RG travel books we've used (Portugal, Italy, Thailand, Tokyo).
As usual, they both overstate their hotel rankings which to me make sense only if you've been sleeping out on the beach from necessity, and now have finally scraped some money together for a room. An exagerration, but I've lost patience with gushing praise for facilities which are usually no better than serviceable and sometimes less than that. And, we're not into spending money on fancy accommodations. Occassionaly the books are on the money, but often not.
On the smaller islands RG usually had more accommodation listings, but occassionally LP did. There were at least two instances when LP had none, just saying that rooms were available.
The ferry schedules in the books, pretty much consistent between them, bore little relation to reality, even though we were there in the high season.
I want to complete with my usual gripe about these and other guide books: we don't know which restaurants and hotels were actually visited by the writers (and by which one) and when. To paraphrase from my review of RG Portugal:
LP is out front in saying that its reviewers do not stay at all the hotels or eat at all the restaurants they list. I would like it if the reviews would be initialized by the reviewers with the date. This would allow us to learn each reviewer's tastes and standards, not to mention seeing which places they actually visited.
One LP writer (not I think an author of this book) in discussing restaurants wrote: "As one of those LP writers I can tell you that it is not physically possible to eat even a 'little bit of a meal' in each of those restaurants :-) What we all tend to do is eat at a broad cross-section within the norms of natural eating times and visit the other restaurants and talk to the owner or even the diners if it can be done discretely. In the same vein we don't sleep at every hotel!"
Talk to the owners for your evaluation! Says it all.
