Getting around in KSA / Visiting Mada'in Salih

Dear all,

In November my Mum and I want to fly to Jeddah stay there two days. Then we want to go to Mada'in Salih followed by a Riyad (especially for a day trip to the edge of the world).

We do not have a driver’s license, so My question now is how to get there.

Taking Uber? How to get around? Are there reliable tour operators?

How many days are recommended for Mada'in Salih?

I know its kinda unusual for western women wanting to visit KSA but we are very curious.

Thank you!

Cheers, Kerstin
