Why not read the cruise reviews for Costa on this site? Just be aware, their newer ships are Carnival clones/copies & some of their older ships are 'converted container ships'!! Buyer beware!
YES! This is an ITALIAN cruise line just the same as MSC. Would you prefer it if all announcements were just in Italian, or are you expecting that it is only the English that should be catered for at the expense of all other nationalities? There are plenty of British/American lines to choose from if it bothers you that much. Cruise lines have to cater to as wide a range of people as possible in order to stay profitable. You only need to please yourself, so choose carefully. Don't be lured into choosing a cruise for its itinerary and then finding that you dislike every aspect of the ship that you are travelling on, as many have done in the past! Happy cruising.
Costa is advertised as an Italian cruise line but is in fact 80 per cent owned by Carnival....we heard from fellow passengers on our recent Costa Cruise that it was not as good as MSC..the announcements are done in several languages and the 'entertainment' was mainly acrobat/dance/mime type of thing. Very disappointing in our opinion as was the food (no nice ice cream and awful pizzas!) But of course everyone likes different things from their cruises!
