Cruise Ship Reviews: Why Size Isn't the Only Story

You type into Google: “Which cruise ship should I pick?” And you get a thousand listicles, each shouting about waterslides, go-karts, and 20-deck floating cities. I get it. The mega-ships are impressive—Royal Caribbean’s Icon of the Seas, the world’s largest, measures 250,800 gross tons and carries up to 7,600 passengers at maximum, with 20 decks and six Wärtsilä dual-fuel engines (Guinness World Records). But let’s be honest: size isn’t everything. In fact, I’d argue that for many cruisers, smaller is better—and the industry’s own data backs this up. So let’s bust some myths and answer the questions you’re actually asking.

Is Bigger Always Better on a Cruise Ship?

No—and here’s why. Mega-ships like Icon of the Seas are engineering marvels, but they come with trade-offs. They’re often too large to dock at smaller ports, meaning you’ll be tendering ashore or visiting only ports that can handle the crowds. The Independent notes that mega-ships function like floating cities with attractions such as waterslides, go-karts, and zip lines, but they may be too large to dock at some ports. Meanwhile, about 73% of oceangoing cruise ships are small- to mid-size vessels with fewer than 3,000 lower berths (CLIA ETP Report 2025). That means the majority of the fleet is not trying to be a theme park at sea. If you want a more intimate experience, better service, and access to off-the-beaten-path destinations, smaller is often smarter.

Are All Cruise Ships the Same?

Absolutely not. The cruise industry is segmented into contemporary, premium, luxury, and expedition categories (The Independent). Contemporary lines like Royal Caribbean, Carnival, MSC, Norwegian, and Disney target the broadest audience with big ships and non-stop activities. Premium lines like Celebrity, Cunard, and Holland America offer mid-size to large ships with a focus on dining and enrichment. Luxury lines such as Regent Seven Seas, Seabourn, and Silversea run smaller ships with high crew-to-guest ratios and all-inclusive service. And expedition cruises are destination-focused voyages to places like Antarctica, the Arctic, and the Galápagos, with brands like Lindblad and Hurtigruten (The Independent). So before you book, ask yourself: what kind of experience do you want? That decision matters more than any single ship review.

Do Cruise Ship Reviews Really Matter?

Yes, but not in the way you think. Most reviews focus on the ship’s amenities—the water slides, the specialty restaurants, the cabin size. But those are just the surface. The real differentiators are itinerary planning, port experiences, and how the ship handles crowds. For instance, PortMiami, nicknamed the “Cruise Capital of the World,” handled a record 8,233,056 cruise passengers in fiscal year 2024, up 12.79% (Miami-Dade County PortMiami). That’s a lot of people moving through one port. If you’re sailing from Miami, you’ll want to know how the embarkation process works and whether the ship docks at the new terminal—MSC World America was named at PortMiami’s new cruise terminal, billed as the world’s largest (MSC Cruises press area). That kind of detail is what a good review should tell you.

Is a Mega-Ship the Only Way to See the World?

No—and this is where I get really opinionated. If you want to see Antarctica, you’re not going to take a mega-ship. You’ll take an expedition cruise, and those are a different breed entirely. In the 2024-25 Antarctic season, 80,455 cruise passengers made landings while 36,769 were cruise-only passengers, according to IAATO vessel reports (IAATO ATCM 47 Paper). That’s a tiny number compared to the Caribbean crowd. And the experience is regulated: IAATO’s management rules limit landings to 100 passengers ashore at one time, require a 20:1 guide-to-passenger ratio, and allow only one ship at a site at a time (IAATO ATCM 47 Paper). That means you get a far more personal, meaningful encounter with the wilderness. So if your dream is to see penguins up close, skip the mega-ship and go small.

Is the Cruise Industry Really That Big?

It’s enormous, and growing. Global cruise passenger numbers reached 31.7 million in 2023, surpassing the pre-pandemic total of 29.7 million in 2019 by 7% (CLIA State of the Cruise Industry 2024). By 2024, that number hit a record 34.6 million, and CLIA forecasts 37.7 million in 2025 and 41.9 million by 2028 (Destination NSW). The industry isn’t just big—it’s economically powerful, generating US$168.6 billion in total economic impact globally in 2023, a 9% increase over 2019 (CLIA 2023 Economic Impact Study). And it’s concentrated: Carnival Corporation alone holds about 32.2% of global passenger capacity, followed by Royal Caribbean Group at about 25.9%, with the five largest companies accounting for just under 80% of global capacity (Cruise Industry News). So when you read a review of a Carnival or Royal Caribbean ship, you’re looking at a product from a dominant player that shapes the industry.

Are River Cruises a Different Beast?

Totally different, and often overlooked. European river cruises carried 1.39 million passengers in the 2024 season, up 14% from 2023, generating 3.54 billion euros in gross ticket sales (CCNR Market Observation 2025). But here’s the kicker: only 46% of European river cruise passengers in 2024 came from overseas, yet they generated 71% of total revenue (CCNR Market Observation 2025). That means the river cruise experience is heavily skewed toward a North American audience that’s willing to pay more for intimate, itinerary-focused travel. If you’re looking for a relaxed, culturally immersive trip without the crowds of a mega-ship, a river cruise might be your best bet.

How Far Ahead Should I Book?

You’re probably not planning early enough. Itinerary planning typically happens 18 months to three years in advance, and travelers often book 12 to 24 months ahead (The Independent). That’s because the best cabins and the most desirable sailings sell out fast. For example, Juneau, Alaska’s busiest cruise port, expects about 1.69 million cruise passengers in 2026, its first season under negotiated daily caps of 16,000 disembarkations on most days and 12,000 on Saturdays (KTOO Public Media). Those caps are a direct response to overcrowding—up to 21,000 visitors used to come ashore on the busiest days (KTOO Public Media). So if you want a summer Alaska cruise, you need to book early to get a spot and to avoid the worst crowds. My recommendation: start researching now, and book at least a year out.

Bottom line

Stop obsessing over which mega-ship has the biggest slide. Instead, decide what kind of experience you want—contemporary, premium, luxury, or expedition—and then read reviews that focus on itinerary, port accessibility, and crowd management. And if you’re open to something off the beaten path, consider a smaller ship or a river cruise. The best move? Book early, and choose the ship that fits your travel style, not the one with the most Instagrammable features.
