If you take an overnight camel trek, you will get to sleep out in the desert and hence save the cost of a night's accommodation!. Be warned though - despite pictures in the tour offices of luxury Bedouin style tents, in practice the shelter is somewhat more basic and bathroom facilities may be somewhat primitive. Still, it is a great experience with campfire, ad hoc drumming/dancing sessions, fire-baked flat bread for breakfast and camel treks back to town the following morning.
Hotel 20 Mars
Is reasonably priced, very clean and relaxed, with simpler rooms downstairs and en-suite rooms on the first-floor all around a cool, pretty courtyard for breakfast, snacks and games of chess.
