Carnival announced its ships will get a look to their hulls that match the new look.

The Carnival Mardi Gras is the newest cruise ship in Carnival's fleet, and it has a hull design that will be copied across to other ships.

The cruise line confirmed the Mardi Gras' hull design will become a trademark feature across the fleet.

Another cruise line has announced plans for a restart outside of the United States.

Holland America Line announced that it will restart cruises from Piraeus (Athens) in August with four departures aboard Eurodam.

The new sailings go on sale beginning May 6, 2021.

Last Wednesday, the CDC sent a letter to cruise lines, updating guidance on restarting cruises from the U.S. as early as this summer.

But what do all the policy updates mean for cruisers anxious to return to the high seas?

Here are the top four takeaways we gleaned from the CDC’s message.

Perhaps the best hint that cruises could actually restart from the U.S. came in a new update from the CDC.

The U.S. Centers for Disease Control & Prevention (CDC) sent a letter to the cruise lines late on Wednesday night providing additional insight and guidance for how cruise ships could restart sailings.

The letter was sent by Aimee Treffiletti, who is the CDC's head of the Maritime Unit for CDC's COVID-19 response within its Global Mitigation Task Force for COVID-19.

Disney Cruise Line has pulled back the curtain on its next new cruise ship.

Disney unveiled the new amenities, activities, and things to do on the Disney Wish, which will set sail in summer 2022.

The next new cruise ship for Disney will feature the first-ever Disney attraction at sea, a dining experience themed to "Frozen", a Marvel cinematic dining adventure, and a Star Wars experience onboard.

If you're a frequent passenger on Princess cruises, you'll want to familiarize yourself with Captain's Circle, Princess' loyalty rewards program, which offers perks that grow in value for cruisers as they ascend up the ranks.

Members enjoy benefits that range from discounts on cruise fares and free recognition pins to exclusive onboard events, complimentary internet access and wine tastings.

This summer, Disney Cruise Line will resume sailing with a series of cruises from select UK homeports aboard Disney Magic; as expected, the line has put a slew of new requirements in place for passengers.

Although the line has suspended North American sailings through at least the end of June and Americans aren't currently allowed on the UK sailings, DCL's health and safety protocols are worth noting, as they could eventually be extended to ships departing from U.S. ports.

If you're looking to make the most out of your cruise vacations, it pays to be loyal to a single line. Over time, you will unlock some benefits meant to make your vacation more convenient and possibly save you some money!

While each cruise line has its own loyalty program they are all built differently. On Royal Caribbean, for instance, you are able to earn two points per night of the cruise if you're sailing in a suite. No matter what cabin you book onboard any Carnival ships, you will only receive one point per night. 

Disney Cruise Line has something big up its sleeve to announce next week.

Disney shared an update on its Disney Wish cruise ship, which it says will "introduce a brand-new, distinctly Disney design concept unlike anything at sea."

Disney Wish is one of the three new Triton Class ships, and it will accommodate among 4,000 passengers and have 1,250 cabins onboard.
