My wife and I have cruised over 40 times,to all regions of the world.This Celebrity cruise was the worst yet.We normally cruise on Princess,Norwegian,Royal Caribbean and Holland America class cruise lines...Not Crystal or Silversea class cruise lines. The main complaints 1.Food.Absolutely the worst quality food ever experienced on any cruise ship or river cruise,badly cooked and served by enthusiastic,totally inexperienced waiters.To add insult to injury there was a restaurant with high quality food,well cooked and served by experienced waiters.This restaurant,the Olympic, was available if you were willing to pay an extra thousand dollars per couple for the food for the duration of the cruise.The huge variation in the quality of the food served between the main dining room and the Olympic restaurant was insulting. In the dining room an appetizer of stuffed mushrooms yielded a dinner size plate containing two black discs 3/4inch diameter.How did they taste ? Who knows,they looked too poisonous to put in the mouth.A dish with mussels displayed six leathery looking mussels,the largest being a maximum of 3/8ths of an inch and also dark black in color.A complaint to the Maitre 'D led to his bringing a new plate of mussels.On the plate were nine more mussels identical to the first batch except for one mussel,2 inches long,plump moist and perfect among the other nine mussels that more resembled rabbit droppings ! Although we were within striking distance of the worlds best mussels,the green New Zealand ones,the Maitre 'D's explanation was that all food for the Australia cruises was supplied to Celebrity from the other side of the world in Florida and thats why the quality was so poor.This from a Maitre 'D ! ! ! 2.Entertainment.In a word "horrendous" Amateurish dancers and bottom of the barrel headliners.In fairness,one act later in the cruise got very high ratings from our fellow passengers but by then we had given up attending the Millenniums theater.On sea days the entertainment was nonexistent except for a number of shows where the entertainers were fellow passengers singing and dancing.Pretty cost effective for Celebrity,right 3.Ports of Call.We missed two of them.Once because the ship had mechanical problems [they existed before we got on the ship] and once because we were told that weather prevented us making it to the next port.However,the Volendam a much smaller Holland America cruise ship that was on the same itinerary as Millennium,mysteriously made it through these "dangerous" conditions".Our guess was that the port charges made it more profitable for Millennium not to go there. In other ports the Volendams passengers took great joy in laughing at the food complaints and "mechanical problems" of the Millenium.We were apparently great entertainment for the other cruise ships. 4.Ships Management.We asked who was responsible for the food and entertainment on board and were told the Hotel Director.When we asked a Maitre 'D if he could arrange for us to meet and talk to him we were told " He doesn't talk to passengers".......What ! ! ! We asked another Maitre 'D in a different restaurant the same question...His response ? He laughed and told us it would never happen.It didn't happen ! 5.Bottom line.. We weren't passengers on a cruise ship.We were cargo being carted from Point A to Point B,to be given minimum cost food,entertainment that cost virtually nothing and ignored if complaints were made.A boring cruise with incompetent managers and a minimally trained,inexperienced crew. I had always looked forward to taking a Celebrity cruise.This cruise ruined that desire.
