Hi, I am traveling to Turkey in August and plan to visit Cappadocia. I will fly out of Izmir to Kayseri either on 8/17 evening(Sunday) or 8/18 early morning (Monday) and leave for istanbul on 8/19 (Tuesday) at night. This leaves me with either 2 days or 1.5 days in cappadocia. Is this enough? I wish to do the hot air balloon ride and see the underground cities. I am not familiar with what else the region has to offer. I came across tour companies that do a 1 day tour of the valley but I'm skeptical about them with regards to time available enjoying the place. Any suggestions are welcome. We are two travelers in their 20's.
