Day 0 - Ferry to Santorini
We woke up early to take the ferry from Athens to Santorini. 7:25 A.M. ferry meant waking up at 4:30 A.M. We said goodbye to Athens and hopped on the 7 hr 30 min ferry, which was actually quite nice.
Voyagers tips: The ferry is a great experience, but it does take up a whole day. We opted to ferry from Athens to Santorini, but take a plane from Santorini back to Athens, just in time for our next flight from Athens to our next destination. By doing so, we also avoided the hassle of finding transportation from the port to the airport.
