If you have two weeks at your disposal and are interested in photography here is what is the Casablanca looks like, and it's definitely worth an overnight stopover. I can recommend my regular accommodation, Hotel Mon Reve, 7 Rue Chaouia, behind the Central Market and ideally located for the CTM bus station and Central Market tram stop for travel to Casa Voyageurs railway station.................

To get to the desert take the train from Casa Voyageurs to Marrakesh, then bus to Ouarzazate where you will find plenty of clues for onward travel to Mahamid Ghozlane, there is one CTM bus daily, you don't need to pay for an expensive tour, it's possible to do it all by yourself on public transport, use the Lonely Planet Guide book or Rough Guide to Morocco for more detailed information.
He travels faster who travels alone!
