Follow the long weekend itinerary; then fly from Istanbul to Kayseri and take a shuttle bus to Goreme, Urgup, or Uchisar to explore Cappadocia. Allow 2 or 3 days to visit the underground cities, the Open Air Museum with frescoed medieval churches cut from the rock, and beautiful Ihlara Valley. Get up early one morning to view the fantastic scenery from a hot-air balloon.
