We did a few excursions and they were all brilliantly organised and worth the expense. In Santorini it was a nightmare trying to get on the cable car to get back down to the port as there were 3 ships in the bay whose passengers were all trying to get down at the same time. We had to queue in blazing sun for over 45 minutes, so if you do go ashore or do the Oia excursion like we did, go straight to the cable car to avoid the queues . . . . . .
At 4.30am on our first night we were woke up by the most horrendous noise under our cabin floor. It was extremely loud banging and creaking like heavy metal being heaved against the ceiling below us. As our floor was shaking with each bang this was really scary so we rang customer service who said they would send someone. About 20 minutes later a man arrived (and of course the noise had stopped by then) and said he would go below and see what it was. He did not come back. About 6.30am it started again, again we called Customer Service and they sent a man to listen but it took so long for him to arrive that he didn't hear it either. A few minutes later another man arrived and wandered off. He returned about an hour later and said he didn't know what it was and for us to call as soon as we heard it again as they would need to send someone a.s.a.p. to hear it so they could find out what it was. This noise disturbed us on and off throughout the week at all hours of the day and night, every time we called no one arrived for at least 20 minutes, if at all so nothing was done about it. At one time about 6 of our neighbours were all out in the corridor and we discovered everyone had been reporting it but no one had received an answer as to the cause of it. As we were approaching Venice on our last day it was really bad so I called again and a customer service lady told me that it was from outside the ship as we were approaching the port. This did not explain why our floor was shaking with each clanging bang from underneath. I have recorded the noise and will upload the sound to you tube along with this review.
The other complaints I have about the Costa Fortuna are;
There was nowhere to go apart from the theatre shows, restaurant or buffet to get away from cigarette smoke. We went all the bars, but did not stay in any as the smoke was so awful. The casino was the worst place for this; we tried to get in there straight after our early sitting dinner, because as soon as the second sitting came out of the restaurants your eyes would literally water from the smoke, so we had to escape to our cabin. I was really surprised by this as the main hazard at sea is from fire - I thought they would have allocated smoking areas but each bar just had a few tables with a no smoking sign on and the Italians ignored them anyway.
The only English channel on the cabin TV was the BBC world news (not good for seven nights!)
Cash wise, it was a total rip-off - everything was vastly overpriced and poor value for money (a Bacardi & coke was 7.30€ +15% service charge so 8.10€ in total!)
If we had known just how many people (3,400) were on this cruise, we probably would not have booked it. When we were at sea the whole ship was heaving with people! We were jostled, elbowed, shoved and pushed along main corridors, especially in narrow walkways such as outside the shops. It was impossible to find a table for lunch in the buffet as it was completely full by about 12.30. We swapped to the restaurant for the last couple of days - the food was better and we got a seat!
The daytime entertainment on deck was all in Italian. It was like a continental 1960's hi-di-hi holiday camp complete on one day with a 'Mr Sexy Legs' competition! Not what we had expected at all!
We will not be cruising with Costa again.
