On this day I decided to visit the desert and see the camels. I booked a tour with a guide, and there are so many small shops where it's possible to book, but I did it online. It's very easy.
In the morning I had time to visit the Souk again, stroll through different streets and see different shops. There are shops with fixed price and others where the price is negotiated, after reaching an agreement, one must take it. Otherwise the vendors get really offended.
