What Are The Biggest Cruise Ships In The World in 2024?

Share

Have you ever asked yourself what the Biggest Cruise Ships In The World Are? It could be perceived as a geeky question, but it’s essential. Incredibly year after year, this answer to this changes. However, we are in 2024, and all of our research is up to date and looking at the latest cruise ship information.

Why do you need to know this? Because one size doesn’t suit all. Some love the larger ships’ sparkle with all the facilities, entertainment venues and bustle. Yet, some love more intimate ships with fewer passengers or a higher passenger-to-crew ratio.

We have done the research and have got all of the information direct from the cruise lines such as the length, weight and how many passengers they can take to ensure it’s as accurate as can be. Passenger numbers can however change yearly as and when cruise lines add or remove cabins from ships; yes, they do that! Then you can choose from the biggest ship in the world or the smallest. Its to you.

So grab a coffee and let our guide help you to decide which is the best cruise ship for you and your cruise vacation.

What Are The Biggest Cruise Ships In The World In 2024?

How Big Is A Cruise Ship?

Cruise ships are HUGE, of course; they come in all shapes and sizes. However, your first time on a cruise ship blows your mind. The current largest ship in the world, Icon of the Seas has 20 decks,7 pools and 9 whirlpools, weighs 250,800 gross tons and is 1,198 ft long.

Cruise ships are floating cities. However, it’s important to remember they are well-designed and easy to navigate. Our advice is to spend the first day getting your bearings, and no matter how old your family or travel companions are, have a meeting place should anyone ever get lost.

The Race For The Largest Passengers Ships In The World

The race for the largest passenger ships in the world has always fascinated me, but there is only one horse in the race; the cruise line with all the biggest ships in the world is Royal Caribbean‘s Icon of the Seas. Costa, P&O, NCL, and Aida follow behind, offering some of the biggest passenger ships.

However, as much as we are huge advocates for Royal and book many cruises with them, we are also aware some cruisers prefer smaller but still new and innovative, and there are plenty of new smaller ships to enjoy too.
