We had one day in Jerusalem, and Reuven was our guide.  He picked us up at the cruise terminal in Ashdod at 9:30 (after patiently waiting 2 hours for us to go through customs) and had us back there by 5:30.  In this short amount of time, Reuven showed us so much!  We saw all the most important places, thankfully!  Reuven was very knowledgeable and knew the city well.  It was amazing!  When we returned to the ship and talked to others who were on big bus tours, we felt so fortunate because we had seen and done so much more than they had (there were 3 of us).  We would definitely recommend Reuven as a guide.  We are hoping to go back to Israel next year, but will stay longer in this wonderful country.
