You can cancel an MSC cruise, but whether you’ll face a penalty depends on when you cancel and the fare type. MSC generally allows penalty-free cancellation within 24 hours of booking, as long as the sailing date is more than 75 days away. After that, cancellation fees apply on a sliding scale based on how close you are to the departure date. https://www.cruisesfares.com/blogs/msc-cruise-cancellation-policy
