We just came back from a 9-day cruise on the Med that took us to Kotor, Corfu, Santorini, Athens, Mykonos, Argostoli, Dubrovnik, and Split.
I HIGHLY recommend Rick Steves Mediterranean Cruise Ports book for folks contemplating a Med cruise but still want some independent travel. Rick’s walking tours for Kotor, Mykonos, Dubrovnik, and Split were perfect! Cruise excursions we did were very campy so we took advantage of any opportunity to explore ourselves. The book came in handy and went with us everywhere. The places that blew me away the most were Mykonos, Kotor, and Argostoli on the gorgeous island of Kefalonia.
To the Rick Steves team - I don’t believe there’s a chapter on Kefalonia but it’s worthy of one. Unbelievably beautiful, especially Myrtos Beach.
