I wenr there in 2013, the tour operator ran a two day excursion which was awesome!
We went to a roman amphitheatre and then headed south to matmata and stopped off at hotel Sidi Dris (Lars Homestead interior) aftet that, we headed Douz which we had a camel ride into the Sahara, after we were put up in a 4* hotel overnight stay.
Next morning up early and crossed the salt flats of Chott - El- Jerid, we did not see or goto the Lars Homestead dome, but crossing was stunning! Our next stop was Touzer, after a tour into an oasis on house and cart, we got in Toyota Landcruisers and across the dunes to thw set of Mos Espa which is awesome, it is all there even moisture vaperatotors, after that it was one more stop ant back to the hotel!
Really loved it and fully recommended, however its alot of time on the road in a coach!
I will post some pics
