We selected a long cruise taking us through the Mediterranean, around the English Channel and through the Baltic sea to St Petersburg. The itinerary was good and because we selected an outside balcony cabin, we were quite comfortable throughout the journey. The ship itself is a large liner and pretty much to the standard you'd expect. Entertainment is, well, entertaining and our cabin staff were friendly and helpful as you'd expect. However it kind of goes down hill from there!
From day 1 the embarkation, on-board organisation and meal experience was disastrous.
(1) Embarkation was 3 hours standing in queues despite some elderly people we noticed having a lot of difficulty. There were no crew members checking on the health and happiness of guests and a bit of care and HR in this regard (maybe some water thrown in) would have done heaps toward the initial experience. Perhaps Costa should realise that the first experience is critical.
