On the way TO Santorini the boat didn't work, so it took us 6 hours to get there, instead of 4 and they didn't gave us anything in return, not even an excuse. Also, I don't like the fact that if you buy 3 tickets together, you are not assured to be seated toghether! That's not right! And the staff aren't particularly friendly! The booking service was good. I like that you can deliver the tickets to a Hotel in Athens! Find a way for us customers to print the tickets after buying them online. Like an airline with airplane tickets!
