For about the same price as an organised trip for 2 you can hire a car and make your own adventure. The hotel is easy to find in Matmata or you can give a local youth a dinar or 2 and he will lead you to it.
Didn't stay over, but the rooms don't look very comfortable. The food here smelt nice & there is a themed bar.
There are a couple of tat merchants outside but they offer no SW related souvenirs, a real shame. Someone is missing a trick by not selling SW fridge magnets etc.
The drive out there is half the adventure. Matmata itself is a breath of fresh air after all the dirty towns you have to drive through to get there. Up in the hills it is clean & pretty little town.
We got there just before the tour buses arrived & had the place to ourselves. The set is very small, if you take a tour bus you will not get any pictures without people in the background.More
