AFAIK they are not talking about campsites, They are closing down the 'desert camps'.I'm gutted if merzouga, has closed we couldn't get there this year, keep us posted
They sell overnight camel/quad trips where you go into the desert and stay overnight at a tented camp, the poor old punters don't realise that they are only a short car ride from where they started because they ve been driven round in circles, have a night under the stars and then next morning they are promptly returned to their hotels and they are so relieved that it was all right that nobody complains, and the next lot get on the camel/quad for their '2 day trip'.
I don't think you will have any problem finding a campsite in Merzouga, in fact you will be beating off the touts as you roll into town.
