I have just found a company based in Nabq and booked a car and driver for the week. Prices start at £50 for 2 people for the week or you can book for the day. Basically call them anytime up to about 1.30am and they will come and pick you up and take you wherever you want. I will be using this service for supermarket runs, jaunts into Naama, Hadaba etc when we are back in Nabq in a couple of weeks. Last month we were totally fed up with the taxi drivers ( will still use the minbuses for local runs ).
I will report back on their service etc.
