Three years ago we stayed at a tent camp in the Wahibi desert in Oman. This was a great experience. Now we would like to stay at one of the Erg Chebbi desert camps for two nights. But we are wondering how things are organized here. Does every tour group and hotel have their own group of tents far away from the others (like in Oman) or do they all stick together? Are the tents really inside the dunes or at the edge of the dunes (near the hotels). Thanks for your help.
