Our rooms had no working A/C (which was promised online only while in ports as they need to physically plug the boat in). Though even when we spent 4 days in Ios, the A/c did not run for a minute of it. If this wasn't enough to make some people angry the tour guide Nate was consistently rude and unhelpful, he cared for no one and was really only interested in having a good time for himself. The one shining light from this trip was kostas, he actually tried his hardest to make sure you were well looked after and got from A to B without being left behind unlike Nate, who would say 'you're an adult, it's your problem if you can't organize yourself' After a week of bad weather and lack of communication as to if we were ever going to go to santorini I bailed on sail Greece and am happy that I did, save your money and do it yourself, cause I know these people won't be able to do it for you!
