I have gathered several books on travel to Egypt, Lonely planets, Passport, Travelers Key, DK eyewitness(second fave) and this one I would rate the best. Its got tons of great pictures, some of which I haven't seen in other books, plus its very full on information. Usually with such books its either tons of info and few pictures or vice versa. This one balances both well. It also has some nice maps and diagrams (tomb layouts, pyramid chambers)a section rating hotels and restaurants, a small section on usefull arabic terms, and a book and movie guide with egyptian themes.
The book starts out with an introduction to the history and culture of Egypt, something many travel guides lack and require a second book for. Then it moves on to points of interest in Cairo, around Cairo, The delta and Suez, Alexandria, Western Desert, Middle Egypt, Luxor, South of Luxor, Red sea and Sinai, then the final part of the book is basically travel tips. Lots of great information. I was happy to see they included a section on the rescue of the temple of Abu Simbel. I've heard of how they moved the temple to save it but was having trouble pondering how such a task could be done. This book explains the actual 'why' the temple was in danger, the various ideas of saving it, and the technique used. Just an example of how in debth this book is.
The pages are nice and glossy as well. And though thick for a traveling book(to take along) its still a reasonable size to fit into a travel bag to take with you.
I would say if you were looking to buy one book only, by far, I'd recommend this one. I like the DK eyewitness book too, but this one I rank higher due to more volume of information and pictures. If you want something slimmer and less in debth I'd go with the DK one, which is still a great book on its own.
