These reviews raise more issues about the prejudices of guidebooks generally and the surprising shortcomings of Amazon, than they do about this individual guidebook.
Virtually every guidebook in existence is dismissive of package tour culture. Whether you want to know where to find english all day breakfasts or how to avoid them, a more even handed approach, explaining precisely that, would be much more helpful than a crude dismissal. The authors and editors are entitled to their personal prejudices, but would widen their readership by keeping them in the background.
It is absolutely wrong for Amazon to sell time-limited guide books, or any similar product such as tax guides, without absolute clarity as to whether it is the latest edition that is being sold.You should go a stage further and advise where an updated edition is on the production line.
Finally, you rather make the point of the chief negative review for its author. He complains the updates are not comprehensive enough and do not reflect reality at the time of issue. That may or may not be fair comment. He wrote that review in 2004.The latest issue of the guidebook came out in 2010. What is the relevance of that review in 2011. Amazon need some system for deleting reviews which are themselves likely to become irrelevant or unfair with the passing of time.
