I'm trying to take my own advice and not plan too much in our 16-day itinerary for Turkey. We've already purchased airline tickets from Istanbul to Izmir to spend time at Ephesus. We're considering renting a car between Dalaman and Antalya to spend time in the coastal region.
The part that we're considering leaving out is Cappadocia as it's a long, overnight bus trip from Antalya to cities near Cappadocia and there isn't a direct flight.
Based on your experience, would we regret going to Turkey and not visiting Cappadocia???
