The Largest Cruise Ships in the World: A Complete Guide for Singapore Travellers

The Largest Cruise Ships in the World

The largest cruise ships in the world are led by Royal Caribbean’s Icon Class, with Icon of the Seas recognized as the world’s largest cruise ship and Star of the Seas joining the same record-breaking family. If you are cruising from Singapore, this guide explains what these mega-ships are like, what they usually cost, and how to decide whether a giant cruise ship is worth it for your holiday.

What makes the largest cruise ships in the world so special?

These ships are floating resorts. They are designed to give you more to do, more dining choices, more entertainment, and more space to spread out. Instead of just using the ship to get from one port to another, many travellers choose these mega-ships as the main holiday experience.

  • More attractions onboard: waterparks, surf simulators, shows, kids’ clubs, and themed neighborhoods.
  • More dining options: buffets, casual cafes, specialty restaurants, and premium dining venues.
  • More cabin choices: inside rooms, ocean-view cabins, balconies, suites, and family options.
  • More entertainment: live productions, music, comedy, games, and deck activities.

The largest cruise ships in the world: key ships to know

Here are the best-known giants in today’s cruise market. For Singapore travellers, these are useful reference points when comparing cruise packages, itinerary style, and overall value.

1. Icon of the Seas

Icon of the Seas is widely described by Royal Caribbean as the world’s largest cruise ship. It represents the newest generation of mega-resort cruising, with a strong focus on family fun, water attractions, and neighborhood-style public spaces.

2. Star of the Seas

Star of the Seas is another Icon Class ship and is presented by Royal Caribbean as part of the line’s record-breaking family holiday lineup. It continues the same big-ship formula with large pool areas, bold dining, and entertainment-heavy itineraries.

3. MSC World America

MSC World America is one of MSC Cruises’ newest large ships and is marketed with 13 dining venues, including six specialty restaurants.

4. Other very large cruise ships

Royal Caribbean’s fleet pages also highlight the scale of its Oasis Class and Quantum Class ships, showing how the industry has moved toward larger ships with more onboard experiences. For many travellers, ships like these are already big enough to feel like a destination on their own.

How much does it cost to cruise on the largest cruise ships in the world?

Pricing changes by season, cabin type, itinerary length, and booking timing. For Singapore travellers, the biggest ships usually cost more than short regional sailings because they are newer, larger, and more in demand.

  • Inside cabins: usually the lowest fare and best for budget-conscious travellers.
  • Ocean-view cabins: a good middle option if you want natural light.
  • Balcony cabins: popular for couples and travellers who want private sea views.
  • Suites: best for families, celebrations, or travellers who want premium perks.

Estimated budget guide:

  • Budget sailing: start from a lower fare in inside cabins on shorter itineraries.
  • Mid-range holiday: expect to pay more for balcony cabins, drinks, Wi-Fi, and excursions.
  • Premium trip: suites, specialty dining, shore tours, and add-ons can raise the total quickly.

For a more accurate budget, always compare the base fare, taxes, gratuities, drinks, Wi-Fi, excursions, and transfer costs. If you want help understanding these extras, read our guide on Cruise Gratuities Explained: Do You Really Have to Pay? and What Does Your Cruise Fare Actually Include?

Are the largest cruise ships worth it?

Yes, if you like having a lot of choices onboard. The largest cruise ships in the world are ideal if you want a holiday where the ship itself is the main attraction. They are less ideal if you prefer a quiet, intimate sailing experience.

Best reasons to book a mega-ship:

  • You are travelling with children or teenagers.
  • You want more shows, pools, and activities.
  • You like trying different restaurants and entertainment venues.
  • You want a cruise that feels like a destination resort.

Possible drawbacks:

  • The ship can feel busy during peak school holidays.
  • Popular activities may require planning ahead.
  • Specialty dining and add-ons can increase your total spend.

Best time to go on a large cruise ship

The best time to go depends on your budget and travel style. For Singapore travellers, the most practical rule is simple: sail during less crowded periods if you want better value, and choose school holidays only if you need family-friendly timing.

  • Off-peak periods: usually better pricing and fewer crowds.
  • School holidays: more family activity, but higher demand.
  • Shoulder seasons: often a good balance of value and weather.

  • 3 to 4 nights: best for a quick break, first-time cruisers, and families with limited leave.
  • 5 to 7 nights: ideal if you want to enjoy more of the ship and not feel rushed.
  • Longer sailings: better value if you care about relaxation, dining variety, and sea days.
