Travelers should consider renting a car for the duration of the trip, as many of the locations are spread throughout Greece. Car rentals range from $30-50 per day, with an average travel time between locations of 3-4 hours.
If you have more time, consider visiting the ancient ruins of Delphi, the island of Mykonos, or the city of Nafplio. If you have less time, consider cutting out a location or two and spending more time exploring each destination in-depth.
The main international airport in Greece is Athens International Airport (ATH), located about 20 kilometers east of the city center.
