In reply to Kemics:
The Moroccans are fairly liberal compared to many Muslim countries, but it's still worth respecting their culture. They don't expect western tourists to 'cover up', but we've heard a few complaints and discomfort from some of the older and more religious members of the community - as a general rule it's worth keeping shoulders and knees covered. This isn't a major hardship, as long trousers work well against prickly vegetation, and T-shirts are fine for climbing in. T-shirt and long trousers works fine in towns and villages too.
I'd advise against strappy tops for the girls, and topless for the boys, as this has caused offence in the past, both in towns and out in the mountains. We even got pulled over once by the cops purely because a girl in the passenger seat was wearing clothing which they deemed provocative!
As someone else already mentioned - you'll see tourists dressed like it's Ibiza, but that doesn't mean the locals approve. Given how closely the climbing community comes to some fairly remote and religious villages it's worth keeping them on side and dressing appropriately.
Dirhams are controlled, but you can get them beyond passport control at most UK airports, or on arrival in Morocco. The Hotel Les Amandiers accepts Sterling and Euros as well as Dirham, but everywhere else you'll need Dirham.
