We started off day 1 in Corfu port overnight due to late arrivals. So missed out on visiting one of the ports. The only time you have air conditioning in your cabin is when the generator is operating. This is generally during the day when sailing or when the chef is cooking. Sleeping in the cabins during the night is unbearable, almost to the point of impossible. There is hardly any air coming through and is quite claustrophobic. The majority of passengers slept upstairs on bench seats and sunbeds. We and another couple ended up taking our mattresses upstairs as there is not enough sunbeds to sleep on. During the night condensation came in and you find that you get extremely wet. We didn't sleep in our cabin at all and when we got back to corfu the last night, we jumped ship and paid for accommodation as did quite a few other couples. The Captain did try to offer the generator to be turned on so that we could have air conditioning at night at the cost of approx 11 euro per person per night of which the majority of passengers accepted. However one couple declined (therefore apparently the majority vote did not rule) so the remaining 22 passengers had to suffer at the expense of one selfish couple. The destinations and the food on board were both really good with magnificent swim stops. The crew were always friendly and attentive and quite aware of the predicament that one particular couple had caused. In fact the captain offered to pay that couple for on land accommodation one night so the rest of the passengers could get a decent nights sleep however they refused. The inability to be able to sleep (only getting 2-4 hours) had a flow on effect and people were exhausted by day 5 which unfortunately put a dampner on the trip. Initially there wasn't alot of information as to where we were going, for how long, meal times and swim stops but after contacting customer support on day 3, they clarified this over the phone so everyone could here and the communication board was updated daily. As mentioned the cruise itself was lovely, it was just a matter of no air conditioning hence no sleep for 7 nights.
