The Best Luxury Cruise Lines Compared: Regent, Silversea, Seabourn, and Oceania

Many guests ask "Which luxury cruise line is best?". The answer is that four lines dominate the conversation: Regent Seven Seas, Silversea, Seabourn and Oceania. Each company excels in different ways.

The inclusion model — the biggest split

The fastest way to distinguish these four lines is to review what each includes in the fare.

• Regent Seven Seas — the most literal all-inclusive. A generous slate of included shore excursions in every port, premium beverages, specialty dining, gratuities, valet laundry, ground transfers when air is booked through Regent, and a pre-cruise hotel on longer voyages. Air is not included in the fare unless a rare promotion says so — I can book flights through Regent's Air department at preferred negotiated rates.
• Silversea — all-inclusive, with a choice of fare tier. Premium beverages, butler service in every suite, gratuities, and basic Wi-Fi. The All-Inclusive Plus fare adds a shore excursion credit on ocean cruises and bundled flights on expedition voyages. Additional excursions, specialty dining in La Dame and Kaiseki, and a streaming Wi-Fi upgrade cost extra.
• Seabourn — all-inclusive on the ship Premium beverages, gratuities, in-suite bar setup, Wi-Fi, and specialty dining are included. Shore excursions and air are extra, though "Ventures by Seabourn" expedition-style tours are included on Antarctica and Alaska sailings.
• Oceania — "luxury-plus," not all-inclusive. The base fare includes specialty dining, still and sparkling water, soft drinks, specialty coffees, gratuities, and basic Wi-Fi.  Promotions vary, and they typically include either wine and beer at lunch and dinner or a shore excursion credit — though this can vary by sailing. The wine and beer at lunch and dinner can be upgraded to Oceania's Prestige Select package, which allows you to order drinks at any time. Excursions are always an extra charge on Oceania. If you are not interested in the wine and beer promotion, you can generally get a shore excursion credit.

Rule of thumb: sticker prices look highest on Regent and lowest on Oceania. Once you add air, excursions, and premium drinks, the four lines land closer together than the brochure suggests. Ask me for a like-for-like quote before you decide one is "more expensive."

Ship size and passenger count

All four lines are small by mainstream standards, yet there are variations.

• Seabourn — ~450–600 guests. The smallest of the four on average.
• Silversea — ~390–730 guests on the classic ocean fleet; expedition ships run 100–240.
• Regent — ~490–750 guests, with some of the most generous space-to-guest ratios in the industry. The ships feel remarkably roomy.
• Oceania — ~670 on the R-class (Regatta, Insignia, Nautica, Sirena), ~1,200-1250 on the O-class and Allura Class (Marina, Riviera, Vista, Allura).

If an intimate ship matters to you, Seabourn and Silversea's smaller size wins. If having more restaurant options appeals to you, Oceania's O-class and Allura Class ships are the largest.

Suites and onboard feel

• Regent — 100% suite and effectively all-balcony (the only exception is Seven Seas Navigator, which still has a small number of window-only suites). The newer ships (Explorer, Splendor, Grandeur) lean opulent — marble, chandeliers, curated art. The signature Regent Suite tops out around 4,400 sq ft with an in-suite spa and personal butler.
• Silversea — 100% suite, butler in every category. Feel is more residential and European: neutral palettes, quieter common areas.
• Seabourn — 100% suite, 90%+ balcony. Yacht-like, warm, and social — the Grill by Thomas Keller on the newer ships is a guest favorite.
• Oceania — mixed suites and staterooms. Not all-suite, not all-balcony on the R-class. Public spaces are warm and residential on Marina and Riviera, or more contemporary on Vista and Allura.

Culinary focus — where each line differs

• Oceania — "The Finest Cuisine at Sea" is the pitch. Four to ten specialty restaurants depending on ship, a Culinary Center for hands-on classes, and Culinary Discovery Tours in port. If food is the top reason you cruise, Oceania has built the most around it.
• Regent — Compass Rose is the main dining room, Chartreuse (French), Prime 7 (steakhouse), Pacific Rim (Asian), and Sette Mari (Italian). All specialty venues included in the fare. Classic, consistently strong.
• Silversea — La Dame (French), Kaiseki (Asian), Silver Note, Atlantide, S.A.L.T, La Terrazza. Ingredient-driven, European lean; La Dame and Kaiseki are the paid options, while the others are included.
• Seabourn — The Restaurant, The Colonnade, and the standout Grill by Thomas Keller on the newer ships. Fewer venues than other lines.

Regent and Oceania share a parent (Norwegian Cruise Line Holdings), which is why their culinary programs share a backbone — I've written a separate deep-dive on that.

Destinations and expedition capability

• Silversea is the only line here with a full expedition fleet — ice-class hulls, Zodiacs, expedition teams in Antarctica, the Arctic, the Kimberley, and the Galápagos (Silver Origin). Best-in-class for polar and remote.
• Seabourn runs two purpose-built expedition ships (Venture, Pursuit) with submarines and Zodiacs — smaller program than Silversea's, yet solid expedition capability.
• Regent is purely classic-ocean — no Zodiacs, no ice class. Where it wins is long, port-intensive itineraries: Mediterranean grand voyages, Asia, Africa, Australia and New Zealand, world cruises.
• Oceania is also classic-ocean, and famous for port-rich, longer sailings — 10-to-24-night Mediterranean and Asia itineraries.The appeal is the destinations, not the ship.

Quick-pick guide

• Pick Regent if you want the most all-inclusive at sea, a generous number of included shore excursions in every port, and the option to add Regent Air at preferred rates for a seamless door-to-ship experience on a long classic itinerary.
• Pick Silversea if you want a quieter European feel, more control over which excursions you pay for, or if expedition itineraries — Antarctica, the Arctic, the Galápagos, the Kimberley — are on your list.
• Pick Seabourn if you want the smallest, most yacht-like ship of the four, a social onboard vibe, and the Keller restaurant.
• Pick Oceania if the cuisine is important to you, if you want a port-rich longer sailing, or if you want a lower entry price and don't mind adding excursions and premium drinks à la carte.

Most clients who sail one of these four eventually sail another. If you prefer, I'll price the sailing you're considering on two lines side by side, with matching air and excursions, so you can compare like for like.
