Look, I've been sailing for years and talking to thousands of fellow cruisers, and there's one conversation that always comes up: which ships should you avoid? After analyzing 2026 complaint data, CDC inspection scores, and thousands of passenger reviews, I'm giving you the straight truth about the most problematic vessels from each major cruise line. This isn't about bashing cruise lines — it's about helping you make smart choices with your vacation dollars.
Every cruise ship has bad days, but some vessels consistently underperform. I've tracked patterns across CDC sanitation scores, passenger reviews on CruiseVoices, and industry incident reports throughout 2026. The ships I'm highlighting aren't just having temporary issues — they're showing systemic problems that affect passenger experiences.
What makes a "problem ship"? Poor CDC scores (below 90), recurring maintenance issues, consistent service complaints, and design flaws that create operational problems. Remember, even a "problem" ship can give you a decent cruise if you know what to expect and plan accordingly.
Carnival Breeze tops my list for Carnival's most complained-about ship. In March 2026, she scored just 86 on her CDC inspection — anything below 90 is considered problematic. I've sailed the Breeze twice, and while the crew tries hard, the ship shows her age in ways that matter.
The biggest issues I've witnessed: embarkation chaos that leaves you standing in the terminal for hours, buffets that run out of popular items by 8 PM, and elevators that break down regularly. The Serenity Adult-Only Retreat on Deck 9 gets so overcrowded it defeats the purpose.
Carnival Elation and Carnival Miracle round out the problematic trio with CDC scores of 89 and 88 respectively. These older Fantasy and Spirit-class ships simply can't handle their passenger loads efficiently.
Pro tip: If you're booked on one of these ships, pack hand sanitizer, avoid peak buffet times (12-1 PM and 6-7 PM), and book specialty dining to skip the main dining room service issues.

Norwegian Prima proves that newer isn't always better. Despite launching in 2022, Prima consistently generates the most complaints in NCL's fleet. The problem isn't age — it's design.
Here's what goes wrong on Prima: The pool deck feels like a sardine can with 3,215 passengers trying to squeeze into spaces designed for much smaller ships. The Indulge Food Hall looks stunning but creates bottlenecks that make getting lunch a 45-minute ordeal. The ship's layout forces you through crowded areas just to move between decks.
I sailed Prima in February 2026, and what frustrated me most was the Haven's exclusive spaces being so small that even suite passengers complained about overcrowding.
The Norwegian Gem also deserves mention — while not generating as many complaints as Prima, her 2026 mechanical issues caused two sailing cancellations and multiple itinerary changes.
Adventure of the Seas leads Royal Caribbean's complaint list with an 89 CDC score in January 2026. This Voyager-class ship from 2001 shows her age in ways that newer Oasis and Icon-class vessels don't.
The main issues: dated cabin bathrooms with shower doors that don't seal properly, dining venues that feel cramped compared to newer ships, and a pool deck that becomes unusable when fully booked.
Symphony of the Seas made headlines in 2026 when safety equipment malfunctioned during a routine drill — not dangerous, but it highlighted maintenance concerns on these massive vessels. At 5,518 passengers, Symphony's sheer size creates logistical nightmares that smaller ships avoid.

MSC Magnifica scored 86 on her May 2026 CDC inspection, but the real problem isn't sanitation — it's cultural disconnect. MSC designs ships for European passengers, and many North American cruisers find the experience jarring.
Common complaints include: dinner service that doesn't start until 8:30 PM, entertainment that feels "foreign" to American audiences, and staff who speak limited English. The ship's layout also confuses first-time MSC passengers who expect Royal Caribbean-style navigation.
MSC Seaside previously scored a shocking 67 on CDC inspection — the worst score I've tracked in recent years. While she's improved, passengers still report issues with food quality and service speed.
Caribbean Princess represents Princess's biggest challenge: an aging fleet that feels outdated compared to competitors. Her 86 CDC score in March 2026 reflects maintenance issues that Princess struggles to address while keeping ships in service.
The problems are subtle but noticeable: cabin carpets that look tired, dining rooms with worn furniture, and public areas that feel dated. Princess's demographic skews older, so they don't invest in trendy amenities, but basic maintenance shouldn't suffer.
Across all cruise lines, I see five recurring complaint categories:
If you're already booked on one of these vessels, don't panic. I've had great cruises on "problem" ships by adjusting my expectations and strategies.
Pack smart: Bring hand sanitizer, seasickness remedies, and backup entertainment. Download Netflix content before sailing in case Wi-Fi disappoints.
Dine strategically: Book specialty restaurants early, avoid peak buffet times, and consider room service for breakfast to skip crowds.
Plan around crowds: Hit the pool deck early morning or late evening, book shore excursions through the ship to guarantee spots, and use stairs instead of elevators during busy times.
Every cruise line has problem ships, but that doesn't mean they can't deliver enjoyable vacations. The key is knowing what you're getting into and planning accordingly. Sometimes the "worst" ship in a fleet is still better than staying home — you just need to cruise smarter.
Remember, cruise lines do listen to feedback and make improvements. Ships that score poorly on CDC inspections often address issues quickly. But if you have flexibility in booking, consider these insights when choosing your next sailing.

Royal Caribbean: Size Creates Problems

MSC Cruises: Lost in Translation
MSC Magnifica scored 86 on her May 2026 CDC inspection, but the real problem isn't sanitation — it's cultural disconnect. MSC designs ships for European passengers, and many North American cruisers find the experience jarring.

Princess Cruises: The Aging Fleet Challenge
Caribbean Princess represents Princess's biggest challenge: an aging fleet that feels outdated compared to competitors. Her 86 CDC score in March 2026 reflects maintenance issues that Princess struggles to address while keeping ships in service.
The problems are subtle but noticeable: cabin carpets that look tired, dining rooms with worn furniture, and public areas that feel dated. Princess's demographic skews older, so they don't invest in trendy amenities, but basic maintenance shouldn't suffer.
The Common Complaint Categories
Across all cruise lines, I see five recurring complaint categories:
- Sanitation issues: CDC scores below 90 indicate real problems with food safety and cleanliness
- Overcrowding: Ships designed for smaller capacities struggling with full bookings
- Service decline: Staff-to-passenger ratios that don't support quality service
- Maintenance backlog: Deferred repairs that affect passenger comfort
- Design flaws: Ships with layouts that create operational bottlenecks
How to Make the Best of a Problematic Ship
If you're already booked on one of these vessels, don't panic. I've had great cruises on "problem" ships by adjusting my expectations and strategies.
