Despite some of these issues, we had a great time on this itinerary (and recommend it). It was our friends who selected it and we were invited to join them after it was established so we had no say. The people of Turkey are incredibly welcoming and friendly and we enjoyed some of the rituals like the Hammam baths and Turkish coffee and clay pot cooking. It was interesting and special to see Cappadocia covered in snow but there were a few limitations getting around on foot due to icy conditions on streets and footpaths. Our travel agent, Tovi, was a dream and made it a point to meet us in Istanbul.
She was incredibly responsive to issues we had along the way. I recommend her highly.
