This guide will explore everything you need to know about the Diamond Princess, from its cruise line affiliation to its onboard experience, itineraries, and what the future holds in the next few years.

Princess Cruises: The Cruise Line Behind the Diamond Princess

Overview of Princess Cruises

Princess Cruises, founded in 1965 by Stanley McDonald, is a premium cruise brand headquartered in Santa Clarita, California. It operates under the Carnival Corporation umbrella, the world’s largest leisure travel company. With a fleet of 15 modern ships, Princess Cruises is celebrated for its innovative technology, diverse global itineraries, and emphasis on personalized guest experiences.

The brand slogan, “Come Back New,” reflects its mission to transform travelers through enriching voyages. Whether sailing to Alaska, the Mediterranean, Japan, or the Caribbean, Princess Cruises focuses on destination immersion, cultural engagement, and onboard comfort. The Diamond Princess is a prime example of this philosophy, offering a blend of Western luxury and Eastern elegance—particularly evident in its Asian-focused itineraries.

Why the Diamond Princess Stands Out in the Fleet

Launched in 2004, the Diamond Princess is a Grand-class cruise ship, one of the largest in the Princess Cruises fleet at 115,875 gross tons. It measures 951 feet in length and can accommodate up to 2,670 passengers with a crew of approximately 1,100. While newer ships like the Discovery Princess and Enchanted Princess feature the latest MedallionClass upgrades, the Diamond Princess remains a favorite due to its:

• Spacious public areas with panoramic views

<

• Multiple dining options, including specialty restaurants like Crown Grill and Sabatini’s
• Extensive Asian itineraries, especially in Japan, South Korea, and Southeast Asia
• Renowned service standards and multilingual crew

Despite being over 20 years old, the Diamond Princess underwent a major dry dock in 2023, introducing MedallionClass technology, upgraded staterooms, and enhanced environmental systems. This modernization ensures it remains competitive in 2026 and beyond.

Princess Cruises’ MedallionClass Experience

One of the most transformative aspects of the Diamond Princess in recent years is its adoption of MedallionClass, a wearable technology that revolutionizes the cruise experience. The OceanMedallion™, a quarter-sized device, enables:

• Keyless stateroom entry

<

• Contactless payment across the ship
• Personalized service (e.g., crew knowing your drink preferences)
• Real-time location tracking for family members
• On-demand food and beverage delivery

For example, a passenger can order a cocktail from the pool deck without leaving their lounge chair—staff locate them via the Medallion and deliver it within minutes. This seamless integration of technology is now standard on the Diamond Princess and is a major selling point for tech-savvy travelers in 2026.

Ship Overview: Features, Amenities, and Onboard Experience

Staterooms and Accommodations

The Diamond Princess offers a wide range of accommodations to suit every budget and preference. There are 1,337 staterooms across 13 categories, including:

• Interior Rooms (168 sq ft): Ideal for budget-conscious travelers
• Oceanview Rooms (180–200 sq ft): With large picture windows
• Balcony Rooms (200–225 sq ft): Private verandas with ocean views
• Mini-Suites (300–350 sq ft): Separate living and sleeping areas
• Full Suites (500–600 sq ft): Spacious layouts with butler service

All rooms feature modern amenities such as flat-screen TVs, USB charging ports, and upgraded bedding. In 2023, over 500 staterooms were renovated with new furniture, lighting, and MedallionClass integration. Travelers in 2026 should book balcony rooms or suites for the best views, especially on Asian itineraries with scenic ports like Hiroshima or Busan.

Dining and Culinary Options

Food is a cornerstone of the Princess Cruises experience, and the Diamond Princess delivers with a mix of casual and upscale dining. Key venues include:

• Sabatini’s: Italian specialty restaurant with handmade pasta and Tuscan wines

Pro tip: Book specialty dining early—Crown Grill and Sabatini’s fill up quickly, especially on longer cruises. The 2023 upgrades also introduced a new “Chef’s Table” experience, where guests enjoy a multi-course meal in the galley with a private chef.

Entertainment and Activities

The Diamond Princess offers a full calendar of entertainment and enrichment programs. Highlights include:

The 2023 refit also added a new virtual reality gaming zone and expanded the library with e-book access via the Medallion.

Itineraries and Destinations in 2026

Primary Regions and Routes

In 2026, the Diamond Princess will maintain its reputation as a premier ship for Asian and Alaskan itineraries. Key routes include:

• Japan & Korea (Spring/Summer 2026): 7–14 day cruises from Tokyo, Yokohama, or Kobe to cities like Hiroshima, Fukuoka, Busan, and Jeju Island. These itineraries often include cultural excursions (e.g., tea ceremonies, temple visits) and seasonal highlights like cherry blossoms.
• Alaska (Summer 2026): 7-day Inside Passage cruises from Vancouver to Ketchikan, Juneau, Skagway, and Glacier Bay. These trips feature whale watching, dog sledding, and glacier viewing.
• Southeast Asia (Fall/Winter 2026): 14–21 day voyages from Singapore or Hong Kong to Vietnam, Thailand, Malaysia, and the Philippines. Ports include Halong Bay, Phuket, and Manila.

Example: A 12-day “Japan & Korea Discovery” cruise (April 2026) departs from Tokyo, stops at Hiroshima (for the Peace Memorial Park), Busan (for the Gamcheon Culture Village), and Fukuoka (for Dazaifu Tenmangu Shrine), and returns to Yokohama. Shore excursions range from $50–$200 per person, with options for private tours.

Unique and Seasonal Itineraries

The Diamond Princess also offers limited-time voyages in 2026, such as:

• Transpacific Crossings: 15–20 day sailings from Alaska to Japan (September 2026), ideal for repositioning cruises with fewer sea days.
• Christmas & New Year Cruises: 10-day holiday voyages in Southeast Asia (December 2026), featuring festive dinners, themed parties, and fireworks in Phuket.
• Grand Voyages: 30–40 day “Around the World” segments, including stops in Hawaii, French Polynesia, and Australia.

For 2026, Princess Cruises is introducing new “Cultural Immersion” itineraries, where guests spend 2–3 days in select ports (e.g., Kyoto, Seoul) with extended overnight stays. These are perfect for travelers who want to explore beyond the typical day-trip model.

Booking Tips for 2026 Sailings

To secure the best deals and cabin choices for 2026, consider these tips:

• Book early (12–18 months in advance): Asian itineraries sell out quickly due to high demand.
• Use a travel agent: They often have access to group rates, onboard credits, and free upgrades.
• Check for promotions: Princess Cruises frequently offers “Free Drinks,” “Free Gratuities,” or “50% Off Second Guest” deals.
• Consider repositioning cruises: These often have lower prices and fewer crowds.

As of early 2025, 2026 Diamond Princess sailings are already 40% booked, with peak demand for July–August Alaska and April–May Japan cruises.

Environmental Initiatives and Sustainability in 2026

Princess Cruises’ Eco-Friendly Commitments

As environmental concerns grow, Princess Cruises has made significant strides in sustainability. The Diamond Princess is a leader in this effort, with initiatives including:

• Liquefied Natural Gas (LNG) Compatibility: The ship’s engines are being retrofitted to use LNG, reducing sulfur emissions by 90% and CO2 by 20%.
• Advanced Wastewater Treatment Systems: Meets or exceeds IMO (International Maritime Organization) standards.
• Single-Use Plastic Reduction: Replaced plastic straws, cups, and utensils with biodegradable alternatives.
• Energy-Efficient Lighting & HVAC: LED lighting and smart climate control systems save 15% on energy use.

In 2026, the Diamond Princess will participate in Princess Cruises’ “Ocean Conservation” program, which includes:

• Onboard lectures by marine biologists
• Beach cleanups during shore excursions
• Partnerships with NGOs like Ocean Conservancy

Carbon Neutral Cruising and Future Goals

Princess Cruises aims to achieve net-zero emissions by 2050, with the Diamond Princess playing a key role. Upcoming 2026 upgrades include:

• Shore Power Hookups: Allowing the ship to turn off engines while docked in ports like Vancouver and Yokohama.
• Biofuel Trials: Testing renewable fuels on select voyages.
• Carbon Offsetting: Offering passengers the option to offset their cruise’s carbon footprint at checkout.

Example: A 7-day Alaska cruise emits approximately 1.2 tons of CO2 per passenger. Princess Cruises partners with South Pole to fund reforestation and clean energy projects that neutralize this impact.

What’s New in 2026: Upgrades, Tech, and Guest Experience

2026 Refit and Renovation Plans

• More plant-based dining options (e.g., vegan sushi, dairy-free desserts)
• Expanded multilingual crew training (especially for Japanese and Korean itineraries)
