Carnival Cruise's $300 Million Safety Upgrade

The Carnival Cruise Lines hope to rebuild their reputation.

They will spend more than $300 million to upgrade their fleet.

The move comes after a string of high-profile problems on their ships.

Carnival is adding more generator power to all of its vessels.

They will keep the toilets, water systems, and elevators running if the power goes out.

They're also developing a new fire safety system and forming an advisory board.

That board will oversee safety and reliability.
