3 of us a traveling to three islands this June and early July. We have accommodations reserved. Should we book our ferry trips now or wait until we are there?
We will be flying into Santorini. We then plan to take a ferry to Milos. Then from there to Serifos and finally one from Serifos to Athens. What do you think?
If you already have your accommodations reserved, then your dates are set, correct?
Then book your ferry tickets as soon as they become available online.
When I've traveled without hotel reservations, in off season, then I planned around the ferry schedules as I went, and it worked fine. Since you have your hotels reserved, then you might as well book ferries, too. If a ferry gets delayed a bit, you still have a ticket.
