If I could give a minus rating, I WOULD. WE BOOKED ON MS HERA and We were held up in Corfu due to late arrivals and advised we would have to stay in port for the night, although the boat does have A/C, we were not allowed to have it running for some reason. It was a very hot day that day and the cabins were extremely hot, and yes we have a tiny little fan in the room to move hot air about. Day 2, resulted in people sleeping outside on the decks to escape the heat from their cabins as it became unbearable and they were unable to sleep in these conditions. Day 3, we have 2 people leave the cruise to go home as they had enough and could not handle they poor show this company has presented. Today when I complained to the company they said that we only pay for 8 hours of A/C a day. This company lies and tries to make the customer at blame, do not waste your money and find someone that is more respected and reputable than Sail in Greece. My advice, AVOID AVOID AVOID
