Our group of 4 would like to travel from Petra to Eilat on a Sunday with perhaps spending a little time in the Wadi Rum area and wonder what the best way to do this would be. Is public transporatation available? With a group 0f 4 would a taxi be the way to go or a tour group such as Eco tours? How can we book these? Should they be booked prior to our arrival in Jordan or at the hotel once in Petra? What stops would you recommend in the Wadi Run?
