With nearly all the cruise ships in the world sitting idle while the cruise industry remains shutdown, why don't the cruise lines shut down cruise ships and park them somewhere?

This idea makes a lot of sense when you think about how much money cruise ships cost to keep them running, even with a skeleton crew.

Most cruise lines have their ships floating off the coast of various ports around the world, but they are all operational and ready to restart cruises if given the chance.

Carnival removed its new health protocols from its website a day after posting them.

The new rules were inexplicably removed from the website and replaced with a general statement from the U.S. Center for Disease Control (CDC).

Carnival posted on Friday comprehensive new rules that included wearing masks, social distancing, and limited shore excursion options.

When Carnival restarts cruises, guests will be required to weak masks, socially distance, and limit shore excursion options.

Carnival announced its new health protocols aimed at keeping guests and crew members safe onboard.

The new protocols are a listing of the rules and things guests can expect to encounter on a cruise ship when they restart.

Canada announced it will not allow cruise ships to enter its waters for one year.

The sum of all fears related to the Alaska and Canadian cruise season in 2021 has been realized with the announcement by Canada's Minister of Tourism that cruises will ban cruise ships until February 28, 2022.

Canada had been banning cruise ships for a few months at a time, but this ban extends an entire year.

The last major cruise line to hold out has cancelled its April 2021 cruises.

MSC Cruises announced it has cancelled its U.S.-based sailings through to and including April 30, 2021.

The announcement was made on Wednesday and affects three cruise ships:

MSC Cruises took delivery of a brand new cruise ship.

The MSC Virtuosa becomes the 18th ship to join MSC's fleet and was delivered to the cruise line at Chantiers de l’Atlantique in Saint Nazaire, France.

MSC says Virtuosa will be the most environmentally-conscious at sea when she comes into service in April.  

The cruise industry adopted face masks for passengers as policy months ago, but the CDC now will require it going going forward.

The U.S. Centers for Disease Control and Prevention (CDC) issued an order that goes into effect beginning February 1 that requires passengers wear masks on all forms of public transportation, including cruise ships.

It also requires people to wear masks in transportation hubs.

Disney Cruise Line announced it has cancelled all of its April 2021 cruises, as well as some May 2021 sailings.

Select sailings onboard the Disney Magic and Disney Wonder in May have been cancelled.

The new round of cancellations are a result of needing time to prepare to meet the guidelines issued by the U.S. Centers for Disease Control and Prevention (CDC).

The full statement by Disney reads as follows:

All the crew members on Norwegian Cruise Line (NCL) and Regent Seven Seas cruise lines will have its crew members vaccinated for COVID-19.

While the decision to require guests to be vaccinated continues, crew members will be completely vaccinated.

A spokesperson for Norwegian Cruise Line Holdings Ltd. confirmed that the policy change.
