Travelers should consider renting a car to explore the country fully, as many of the destinations are spread out. Alternatively, there are many affordable bus and ferry options available. The cost of renting a car ranges from 30-50 Euros per day, and travel by bus or ferry costs between 5-20 Euros per trip.
Travelers with more time may want to consider adding a trip to Santorini, the most popular destination in Greece, or visiting the ancient city of Knossos on the island of Crete. For those with less time, it's recommended to cut the trip down to 8-10 days and focus on the most highly recommended destinations.
