First, the good points.
Beautiful ship, very clean, cabins excellent, wonderful theatre, buffet food excellent, destinations worth visiting again (but NOT on a cruise ship), catering, cabin and bar staff wonderful (virtually all Indonesian, really nice people).
The bad bits far outweigh the good bits and made it very difficult for us to enjoy the holiday. There were 8 of us in 4 cabins. The ship catered for 2500 people, over 50% of which were under 45 with quite a few children (despite our booking being within school term). The pool area was mobbed, with inane dance lessons from the entertainment team using a tannoy, extreme noise. As a result we never got to use the pool area. At Santorini, 3 cruise ships anchored at the same time. We spent 4 hours on the island, 2.5 of which were spent queueing for the cable car and tender to the ship. It was chaotic and quite unnerving; people can be very ill mannered when in a mass queue.
Bar prices were very expensive with a mandatory 15% service charge on top of everything purchased. Excursions are expensive, average 64 per person with poor value (bus rides with a guide in the main).
For every trip, people had to be coralled and queued. Management are Italian and, with some exceptions, very arrogant. On our last trip (to Venice) there was an inordinate wait on the internal stairs of 20 minutes while the tenders came to the ship. We should have been allowed to wait in the lounge. No explanation or apology was offerred. When queried on it, they still tried to justify it.
Food in our allocated restaurant was very meagre and much too formal. I've eaten bigger sandwiches than ALL the main courses we were presented with. It is much more sensible to eat in the buffet, without the formality.
However, use the buffet some time after it opens. A massive hungry and unruly crowd of cruisers descend on it like locusts at first opening. This is especially true at early breakfast, where cruisers are going on early excursions; not a place to be!
All of the 8 people in our group feel the same and as a result would not travel on an Italian managed ship
