Consistent with the US Centers for Disease and Prevention protocols, Carnival Horizon arrives in Miami this week, and Carnival Breeze will be the next ship back to the US.

Carnival had previously canceled certain other itineraries on four ships (Magic, Paradise, Valor, and Victory/Radiance) that are scheduled for required drydocks in the first half of 2021, with the plan to return them to operations after maintenance work and upgrades are completed. Also previously canceled were operations in Australia through March 2.
