A little too busy to post and I don't have the pics uploaded yet but ...
Istanbul: fantastic hosts, noisy hotel, good class in a spectacular setting by a huge suspension bridge spanning Europe and Asia ... pretty cool.
Athens: much better hotel and neighborhood than my last visit full class, not much happening besides work but you have to love a cold beer beside a rooftop pool with a sweeping view of the city and the Parthenon, don't ya?
