I believe that we'll receive more informations concerning a lift to Al Khor and showing us locals around.
At the moment, my family will join me later, so I don't need a car as far as the bus is still running from Al Khor to Doha.
Apart from this, good idea Hels, we can agree on a sign to recognise each other. :-)
We are already 9 at the moment if my calculation is right...
