Fact of the matter is the older you are, the more likely you will require medical assistance. It's one thing if you are on a cruise designated for the purpose of hosting retirees for long periods. It's another thing to think you can get away with it by simply booking and booking on a
DCL ship for huge period of time. People get sick and hurt on DCL cruises all the time, but the difference is these are not chronic health problems that may require specialized care. The system is not set up for that.
