2 or 4 people to join Southern Morocco circular to ur to Erg Chigaga Sahara 8-11th April

Hi There, I'm looking for 2 or 4 people to join myself and my 13 year old son Stanley , probably on the tour, link posted below. It is a little more interesting than many I have looked at, as the route south is via the under visited (in my opinion!) Glaoui Kasbah at Telouet, then Ait Benhaddou, to Agdz, before heading to Erg Chigaga for the Desert night experience and camel rides. The return via Foum Zguid, and overnight at the Fint oasis near Ouarzazate, before return to Marrakech. Not too much retracing of steps! This is four days and three nights, leaving Marrakech on 8th April, returning on the evening of 11th, in time for our flights back to UK. Based on 6 persons total, the cost would be£235 pp, or for 4 persons 295. For just the two of us, it would be a prohibitive £395 pp. I am happy for tour to be conducted in English, French or Spanish, by consensus! Please get in touch if you're interested Beds, breakfasts and evening meals are included, and all travel and insurance. http://www.mhamidvoyages.com/offres.php?id=2_38 )
