Boarding was simple—it always is when you're the last to board. We reported our missing bag to the Costa purser; they contacted Alitalia on our behalf with a full description of the bag; they gave us an overnight kit and slippers, loaned us two bathrobes, and comped out laundry (express service!) for our entire stay aboard.
No,Alitalia has yet to return or reimburse us for our luggage; we've tried contacting the phone numbers and email addresses on their website, but all are out of service.
Cabin incredibly spacious; one of two diagonal-shaped cabins over fantail. We could and did sit in the window. Bed quite comfortable, firm mattress. Warm comforter. Excellent temperature control. Very helpful cabin stewardess. But woke one morning to the smell of bacon--and, alas, breakfast was not served for another hour.
Choice of buffet sit-down breakfast (with possibility of ordering over-cooked eggs) or buffet on upper level with truly wonderful omelets. Breakfast best meal of the day.
Dreadful pizza always available. Was it us or the Pizza? I asked an Italian passenger who said, "Pizza was dreadful." (Majority of passengers were European--Italians, French, German, Brits and made for interesting company.)
Entrees, appetizers and soups were almost always inedible. The exception were the wonderful Italian cheeses.
Serving staff surly and quick to forget requests for water or tea.
Music everywhere, afternoon and evening. We danced each night and many joined us on the floor--musicians excellent. (And after the ballroom dancers left, the discos opened).
No free in-room movies or lectures.
Our itinerary was excellent, but Costa, quick to sell their own tours, provided little aid on getting to town. The exception was free shuttle in Civitavecchia and $6 per person shuttle in Barcelona.
Valleta was home to the Knights of Malta and their headquarters is not to be missed.
If you're not careful, your cab driver will take you not to the ruins of Carthage but to another outdoor market. Our driver did throw in a tour of the Presidential palace as well as the innumerable villas and apartments reserved for the President's cronies. By begging, we also got to see some ancient Roman era cisterns.
