Istanbul → Ankara → Konya → Göreme works without a rental car, using three intercity coaches and local public transport. The nine nights divide 3 + 2 + 2 + 2: two full days in Istanbul, one each in Ankara and Konya, and one in Göreme. Daylight transfer days carry the longer rides; arrival and departure days have lighter plans.
Ankara adds a contrast between the republic’s memorial and older Anatolian collections. Konya brings the Mevlana Museum and Seljuk architecture into a compact walking day. Both stays have a cultural purpose, rather than serving only as breaks on the way to balloons. The Istanbul–Ankara move needs a full travel day, so save the capital’s major visits for the following morning.
Choose the final coach to Göreme’s own terminal where possible; a Nevşehir arrival needs an onward ride. Central Göreme makes its one full day usable on foot. This route suits travellers content with a local museum-and-valley day, rather than distant trailheads or several underground cities. YHT trains can replace the first two coaches after their tickets and costs are confirmed separately.
