Introducing the Giant of the Seas: Princess Cruise Lines’ Biggest Ship

When it comes to luxury, scale, and innovation in the cruise industry, Princess Cruise Lines has long been a name synonymous with excellence. For decades, this iconic cruise line has delivered unforgettable experiences to millions of travelers, combining elegant ocean voyages with cutting-edge amenities and world-class service. But as the cruise industry continues to push the boundaries of engineering and design, one question stands out: What is Princess Cruise Lines’ biggest ship? The answer isn’t just a matter of size—it’s a testament to the evolution of modern cruising, where ships are not just vessels, but floating cities offering everything from Broadway-style shows to gourmet dining and immersive technology.

Enter the Discovery Princess, the crown jewel of Princess Cruise Lines’ fleet and the largest vessel the company has ever launched. With a gross tonnage of 143,700 and the capacity to carry over 3,600 guests, the Discovery Princess redefines what it means to sail in style. But size isn’t the only factor that sets her apart. From her state-of-the-art MedallionClass technology to her expansive public spaces and family-friendly attractions, the Discovery Princess represents a new era in cruising—one where personalization, comfort, and sustainability go hand in hand. In this deep dive, we’ll explore everything that makes the Discovery Princess not just the largest ship in the fleet, but also one of the most advanced and guest-centric cruise ships in the world.

The Rise of the Discovery Princess: A New Era for Princess Cruise Lines

From Concept to Maiden Voyage

The Discovery Princess is the sixth and final ship in Princess Cruise Lines’ highly successful Royal-class series, a line that began with the Royal Princess in 2013. Designed by the renowned shipbuilders at Fincantieri in Italy, the Discovery Princess was delivered in 2022 after years of meticulous planning and construction. Her name pays homage to the legacy of exploration that has long defined the Princess brand, with “Discovery” symbolizing the journey of uncovering new destinations, cultures, and personal experiences.

Her maiden voyage took place in March 2022, embarking on a 15-day transatlantic journey from Rome to Ft. Lauderdale, Florida. Since then, she has sailed on a variety of itineraries, including Caribbean cruises, Alaska voyages, and European explorations, quickly becoming a favorite among seasoned cruisers and first-time travelers alike.

Why Size Matters in Modern Cruising

At 143,700 gross tons and measuring 1,083 feet (330 meters) in length, the Discovery Princess is not just the biggest ship in the Princess fleet—she’s also among the top 20 largest cruise ships in the world. But what does this mean for guests? Larger ships offer more space, more amenities, and more opportunities for personalized experiences. With over 19 decks and 1,830 staterooms, the Discovery Princess can accommodate 3,660 guests at double occupancy and up to 4,200 at maximum capacity, supported by a crew of approximately 1,346.

However, size isn’t just about numbers. It’s about how that space is used. The Discovery Princess was designed with intelligent space utilization in mind, ensuring that even at full capacity, guests never feel crowded. Wide promenade decks, multiple dining venues, and expansive lounges allow for a more relaxed and enjoyable experience. As one cruiser noted, “Even on a full ship, I never waited more than five minutes for an elevator or a table.”

Engineering Marvels and Sustainability Innovations

Beyond her impressive dimensions, the Discovery Princess incorporates several eco-friendly technologies that reflect Princess Cruise Lines’ commitment to sustainability. The ship is powered by Liquefied Natural Gas (LNG)-ready engines, meaning she can be retrofitted to use LNG in the future, significantly reducing emissions of sulfur oxides (SOx), nitrogen oxides (NOx), and carbon dioxide (CO2).

Additional green features include:

• Advanced wastewater treatment systems
• Energy-efficient LED lighting throughout the ship

< li>Smart HVAC systems that adjust based on occupancy

• Waste-to-energy incinerators with heat recovery

These innovations not only reduce the ship’s environmental footprint but also contribute to cleaner air in port cities and marine ecosystems—a critical consideration as the cruise industry faces increasing scrutiny over its environmental impact.

MedallionClass Experience: The Future of Personalized Cruising

One of the most revolutionary aspects of the Discovery Princess is her integration of MedallionClass technology, a wearable device (the OceanMedallion) that transforms the cruise experience. This palm-sized, waterproof disc connects guests to a network of sensors and AI-powered services across the ship, enabling:

• Keyless stateroom entry—simply wave the Medallion at your door
• Contactless payments—no need to carry cash or cards
• Real-time location tracking—find friends or family on the ship
• Personalized recommendations—based on your preferences and past behavior
• On-demand service—order drinks or food from anywhere on the ship

For example, if you’re relaxing in the SkyLight pool area and decide you’d like a piña colada, you can use the OceanMedallion app to order it directly to your lounger. Or, if you’re exploring the ship and forget where your stateroom is, the app can guide you with turn-by-turn directions. This level of personalization is unprecedented in the cruise industry and is one of the key reasons the Discovery Princess stands out.

Staterooms and Suites: Comfort and Style at Sea

The Discovery Princess offers a wide range of accommodations, from cozy interior staterooms to expansive suites with private balconies. All staterooms are designed with modern elegance, featuring:

• Plush bedding with high-thread-count linens

• Exclusive access to the Sky Lounge, a private retreat with complimentary cocktails and canapés

Even standard balcony staterooms are generously sized, with an average of 230 square feet—larger than many mid-tier hotel rooms. And thanks to the MedallionClass system, each stateroom can be customized to your preferences, from lighting and temperature to pillow type and wake-up calls.

Public Spaces and Amenities: Designed for Every Guest

The Discovery Princess boasts an impressive array of public spaces designed to cater to every interest and age group. Highlights include:
