This probably is still one of the best travel guides for Morocco. The maps are excellent, lodging info useful but where it remains unsurpassed is trekking information. Info on how to structure 1-7 day treks, where to eat and sleep and how to find your way across the difficult terrain is excellent, imo better than what I've seen in other LP guides. Less effort seems to have been expended on interesting info on cities & their history; sometimes, as in the case of Marrakesh, the prose borders on corny. I bought the Kindle edition as well and can;t understand why the authors did not add little videos of locales or clips of music.
More could be said about the Morrocan people and about music of which there are many many distinct (incredibly rich and powerful) forms that include Gnawa, the exorcism ritual music of former black slaves (it's the Moroccan "blues").
Moroccans are a diverse, proud and beautiful people. A little kindness and generosity go a long way - too often have i seen tense fat lilly-white Westerners walk around nervously clutching bags strapped on their chests, evading payment of a few MADs for a street performance and then get fleeced while buying a carpet or a lamp, or get screwed by taxi drivers who are in fact scoundrels that are almost impossible to evade. Faced with professional beggars, tourists tend to clam up and willfully ignore real cases of hardship that one sees on city streets or in some Berber villages. No, one should be a human amongst human beings, revel in sights, smells, vibrations and emotions that are Morocco. And when it comes to large purchases, go for the jugular and haggle without mercy. Haggling is an emotional-financial-cleverness extravaganza that Moroccans seem to live for. Don't disappoint them. They'll still get your hide and that's OK too.
