We sailed last July on the Celebrity Silhouette - during the Europe-wide heatwave - from Rome to Naples, Malta, Mykonos, Santorini, Kusadasi and Athens.
The ports were all excellent and we particularly liked Malta, but it was too hot so we didn't spend as much time ashore as we would have liked. Celebrity couldn't do anything about the heat but the onboard air-con was perfect. I usually find it too cold! I could even go into the dining room at night without a wrap which was a first for me.
We were very impressed with Celebrity overall. We had a problem with youngsters in the adjacent cabin which was dealt with very promptly and efficiently by the security staff, even though it was the middle of the night. The staff on the Silhouette were friendly and interacted with the guests, which hadn't been the case when we sailed on the Equinox a few years previously; on that occasion we were definitely underwhelmed by them.
We had a balcony cabin on the starboard side, which we chose particularly because we wanted to be on the 'right' side for sailing into Venice at the end of the cruise. It was a good move! We had stunning views all the way along the Guidecca canal into port. We would, however, have liked to have a coffee/tea maker in the cabin. I know room service is free but the convenience of do-it-yourself can’t be overestimated.
The food was very good, although, as is usually the case with American cruise lines, sadly lacking much in the way of vegetables. The steaks in particular were excellent. We had requested a table for 8 at the second sitting. In fact we were on a table for 10 and had the best of table-mates so we really looked forward to dinner each evening. Celebrity have a lunch-time buffet, usually on a sea-day, which was excellent with superb displays of food and ice carvings.
The ship was very well maintained and everywhere was sparkling. The only downside was the lack of enforcement of hand-washing. On other cruise lines you have no choice but to use the hand sanitizers on entering the dining room, but this unfortunately wasn't the case on Celebrity. Luckily there was no outbreak of noro-virus, but it would definitely make us think twice before we cruised with them again.
The entertainment left quite a lot to be desired. We usually went to the theatre with our table-mates who were from the USA and we were all in agreement about the standard. The one exception was our own Sam Kane, from the UK, who proudly boasted that he is married to Linda Lusardi, which, of course, was totally lost on the Americans. He was excellent. He was very funny, has a very good singing voice and was by far the best show we went to.
There was an acapella group who performed in various timeslots and venues around the ship. They were well worth listening to and we even went half way though changing for dinner one night to the other end of the ship to hear them as they were so good.
