A day at sea 💯 enjoying a lot

A sea day on a cruise is precisely what its name implies: it is a day spent solely on the sea. A cruise ship on this particular day doesn't make any stops and simply sails the seas, making its way to the next port.

You may notice sea days listed on your cruise itinerary as "cruising" or "at sea." While they may appear differently on paper, they all mean the same thing: you're cruising on the open water the entire day.
