Carnival Horizon arrives to Miami this week
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. In total, 16 Carnival ships are currently following the CDC process for an eventual resumption stateside in 2021, including Carnival Conquest, Dream, Ecstasy, Elation, Freedom, Glory, Liberty, Miracle, Panorama, Pride, Sensation, Sunrise, Sunshine and Vista.
Mardi Gras, which is under construction in Finland, will also enter service in 2021.
Prior cancellations
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.
'We are committed to meeting the CDC requirements and keeping our guests and business partners informed of our progress,' Carnival President Christine Duffy said, adding her appreciation for the support of customers, travel advisors, business partners and officials in homeports and destinations.
