"Due to the nature of a cruise vacation,
itinerary changes sometimes become necessary for safety, weather or other reasons beyond the control of Carnival. If the itinerary change is for reasons beyond Carnival’s exclusive control, including but not limited to safety, security, weather, strikes, tides, hostilities, civil unrest, port closings, emergency debarkations of guests or crew, late air, sea, car or motor coach departures or arrivals, mechanical breakdowns or problems not known to Carnival, itinerary changes consistent with U.S. State Department travel warnings / advisories or other applicable US or foreign governmental advisories,
guests will not be provided any compensation. Guests electing to cancel will be subject to the standard cancellation terms. "
