We will be in Athens for 3 full days. We are staying at the O&B Athens Boutique Hotel near the Acropolis. I wanted to spend one full day in Athens and then spend a day visiting Delphi and another day driving down to Cape Sounion.
Personally I love renting cars and finding my own way to places, being able to simply stop at any beach on the way and go at our own pace is a must, and I hate organized tours. So if we rent a car is it realistic to find parking in central Athens?
