I've been watching the ferry schedules closely as we'd like to make more definitive plans for our vacation. We arrive on Milos from Athens by Aegean Airlines and have been trying to decide itinerary with the goal of visiting Milos about 6-7 days total, Sifnos about 5-7 days, and Folegandros about 3 days. We arrive on May 30 and depart on June 15. At the end we fly out of Milos back to Athens, so we have to backtrack. Now I see that there are two slow ferries on June 5 to Sifnos at about the same time: NEL (12:25-14:35) and Adamantios Korais (12:20-13;35). What are the differences between these ferries? Will they really run at the same time? We then plan to take the 'Adamantios Korais' to Folegandros on June 10, and then the NEL to Milos on June 13. What are your thoughts on the order of the islands as well as the time allocated for each? Thanks in advance for any suggestions.
