Summer Vacation on Greek Coast

Hello everyone! :-)

My girlfriend and I are planning a summer holiday in Greece for the upcoming summer. Until now, we’ve spent our holidays on the Croatian coast, so organizing a trip was never a challenge due to the proximity (we’re from Sarajevo, Bosnia and Herzegovina). However, since this will be our first time vacationing in Greece, we don’t know much, and we don’t have any close friends with experience either.

We haven’t booked our stay yet, but we’re planning to work on that at the beginning of next year. At the moment, we’re looking at Zakynthos, Lefkada, or Kefalonia! Does anyone have experience vacationing on any of these three islands? If someone has recommendations for accommodation or a specific area where most beaches are easily accessible with a car, we’d really appreciate it. Any advice, even general, would be helpful!

Thank you in advance! 🙂
