Travellers need to consider that they will need a combination of public transport such as metro or bus services to explore major attractions in Athens. The cost of the transportation varies but you can expect a daily budget of around €5-€10 per person. Inter-island travel involves ferryboat services, which can cost €20-€30 per day, and travel time will depend on the destination.
To maximize your 10 days vacation to Greece, it is recommended that you should plan your itinerary according to your preference, interest, and budget. If you have more time to take, you can add more days to each attraction or extend your stay in certain islands. Alternatively, if you want to shorten the trip, it is recommended that you skip some of the smaller islands or cut short on a day's journey.
