Which cruise lines does Carnival own?

[Host Mike]

"Nine cruise lines fall under the Carnival umbrella, making it the largest parent company in the cruise industry."

Aida Cruises
Carnival Cruise Line
Costa Cruises
Cunard Line
Holland America Line
P&O Australia
P&O Cruises
Princess Cruises
Seabourn Cruise Line

"Princess was rolled under the Carnival umbrella in 2003 when Carnival Corp. combined with P&O Princess Cruises.

Princess' ships walk the line between courting older passengers with their connection to popular 1980s television show "The Love Boat" and staying current with technological advancements that include the industry's first fleetwide wearable, the OceanMedallion. As a result, the line appeals to a variety of passengers of all ages, including couples hoping to share a romantic vacation."

From what I've been seeing about the Icon of the Sea, Princess better get their act together very quickly. RCCL is outdoing the competition by leaps & bounds.
Not that I need the water slides or bumper cars but it sure does look appealing even to the older folks.
