My husband and I will be spending 5 days on Sifnos in mid-August 2014, and are looking to book a ferry back to Piraeus on Saturday, August 16. We have a plane to catch early in the morning on Sunday the 17th (I know, I know, but it was the only option). A few questions about the logistics of this:
1) It looks like there are two companies that run the route, Aegean Speed Lines (faster) and Cyclades Ferries (slower). Is either of those companies more consistently reliable given that we don't have a lot of buffer for our flight back to California?
2) If there's no difference in reliability, is one a nicer experience?
3) Any recommendations for good sites to purchase tickets from?
