Since we were cruising in January, my main concern was about the weather but it turned out to be dry, sunny and the sea was calm throughout the cruise.
Overall impression of Costa is very positive. We are a family of 2 adults + 1 teen (15 years old) and everyone was kept busy by Costa's staff: the kid was off for the Teen Zone, my husband was into leaning Italian language and I was happy with Latino dance lessons.
The ship is new and cabins are spacious.
spacious cabin, nice view, quiet and short walking distance to the elevator to the breakfast buffet restaurant.
