Turkish Airlines Free Istanbul Tour

Turkish Airlines offers free tours of Istanbul for passengers connecting through Istanbul en route to other destinations.  You must have at least a 6 hour layover.  The tour is completely free including transportation, food, museum entry fees.  This seems like a great way to see a great city.  Turkish Airways has been offering some pretty attractive deals from the US in an attempt to further expand their market share.
