My friend and I will visit Doha in mid Sep 2011 and wish to join a tour for The Sand Dunes Half Day Safari. I’ve gather the tour information from several tour agents and learnt that the minimum number of participants is 4, but we are 2 persons only and the cost is high. I’m advised to pay for 4 persons if we wish to join the tour. Is there any group tour for us so that we could share the cost with others?
