Aug 1. Carnival Cruise Line and Royal Caribbean International both announced that they are adjusting certain protocols to reflect the lifting of CDC requirements for the U.S. cruise industry. Other brands are expected to follow this soon.
Carnival said changes will be made in phases, with the first of these updates effective on August 4, 2022 and focused on short cruise itineraries of five nights or less. More changes will be announced shortly and all changes are subject to any requirements of destinations on the itinerary.
Effective for embarkations on or after Thursday, August 4: No pre-cruise testing for fully vaccinated guests booked on cruises with itineraries five nights or less; pre-cruise testing for itineraries six nights or
longer can be conducted three days before departure; there will be no in-terminal testing for unvaccinated guests on day of departure, but all unvaccinated guests ages 2 and older must provide proof of a negative result of a lab-administered or supervised self-administered antigen COVID test taken within three days before embarkation.
