We are currently booked on the Poesia for 10 days on Sept 6, 2025 out of Copenhagen. Our friends decided to join us, but the cruise is no longer showing available. It is showing available the next day out on Warnemunde for 11 days at a much higher rate. Can it really be sold out a year and a half in advance? We booked about a month or so ago and there were plenty of cabins in all categories. This seems odd or is it just a typical MSC thing? It has been like this for over a week.
