I am trying to plan a trip over the holidays with my 16 year old son. I only have about 7 or 8 days and am considering either Istanbul or Jordan (or maybe both, if doable). Any suggestions on which location would be better. Is there enough to see in Jordan besides Petra? My son is very interested in history - but will not want to spend all his time looking at mosques. Can I travel to either place alone and hire guides once there - or is a package tour necessary.
