My first RS guide was a 2006 Italy that I scavenged in 2009 - a couple sections had been cut out and the book had been abandoned. My second was Istanbul, as part of the tour package for my Turkey tour. Both were very useful, so when I was visiting the U.S. I bought the Madrid & Toledo guide for a trip to Spain, again worth the money. RS books aren't sold here, so when I planned a return visit to Barcelona, I bought the Barcelona guide in the Kindle format. Again, it was very helpful, and I liked being able to bookmark pages and have it in my pocket on my iPod Touch. Then I was in the US again this summer with a $20 Barnes and Noble gift card . . . what to buy? I headed for the travel section and saw the RS Krakow, Warsaw & Gdansk (which I'm hoping to see this fall), so I grabbed it.
When I registered for the 2017 Greece tour, I got my $100 credit just after the winter sale began, and I was so excited to be able to buy 4 guide books for about $4 ($38 for shipping). I bought Greece (of course) and Budapest (planning for the fall with Poland) and then Italy since I'm going in February and certainly not for the last time and with the leftover change, France - since my first "driving through rural France" trip last year, I'm chomping at the bit to see the rest of the country.
The shorter books are fine - even at over 700 pages, the 2006 Italy was on thick paper. The larger books (Italy at over 1200 pages and France at almost 1200) are anything but fine. If I had paid money for them, I would be really unhappy. There wasn't anything in the travel store that I needed, so had I known then I'm not sure what I would have chosen instead - maybe shorter guides to places I may travel to in the future.
What don't I like? The pages are so thin, it's sometimes hard to turn them. I highlighted a phrase and it bled through to the other side, so it looks like something on flip side is also highlighted. I'm going to Naples. I tried to photocopy the map of the city walk, but the print from the reverse side bled through and the map is illegible. After I typed the entire walk onto a Word doc (took over an hour) so I'd have it on a word doc that I can take with me, either on my Touch or on paper, I tried to remove the page with the map from the book. I have bent the book back to try to pull the page out, but I'm afraid it will just tear somewhere in the middle. The paper is too thin to try to slice it out without slicing other pages too. [one of the few sections of my 2006 guide that's missing is this walk!]
It's time to divide the long guides into two books each. I'm sure better minds than mine could fine practical ways to split them and produce useful books.
In the meantime, my advice is to consider carefully before buying one of them. And consider choosing the kindle version. Many of the RS guides are available in kindle on Amazon. I found it very easy to use the Barcelona guide on my home computer when I was planning. I could highlight text, make notes and copy sections on to word docs to print out, including the pretty colored maps.
