Might compare Amman's originally being built on seven hills to the ancient city of Rome, although Amman now spans 19 hills or so, and then tie in the ancient Roman remains found there. Might talk about how the city has expanded due to the frequent influx of refugees since 1948 and what makes the area attractive to refugees. Might also write about shopping becoming a big past time in this area and the number of mega malls popping up the last few years.
If I were visiting there, I would go see Petra. You might remember seeing it in one of the Indiana Jones movies where Indy meets the man guarding the Holy Grail. That scene was shot in the Rose City of Petra. Very cool place.
Also might talk about how the geography affects the area's climate, which from all reports is pretty darn nice.
Good luck.
