Most cruise lines were watching the fires in Greece carefully, not so much as a danger to the ships or their passengers, but rather so they wouldn't dock at a given port and have no sightseeing available to passengers.
When surveyed earlier this week, most lines were not reporting changes to their itineraries, however some said some individual shore excursions were canceled in selected ports. Costa was the only line we surveyed which had scheduled changes. Costa Serena replaced their call at Katakolon with one at Mykonos, and Costa Mediterranea called at Corfu in place of Katakolon.
Good news comes from our contacts at MSC Cruises. They advised us this morning that the Olympia historical ruins have now been reopened to the public, and they did not find it necessary to modify any of their ships' itineraries.
