Ship Classes and Design
Mariner belongs to Royal Caribbean's Voyager class, known for larger ships with extensive amenities. Brilliance comes from the Radiance class, which focuses on a more traditional cruise experience with plenty of glass and ocean views.
The age difference is minimal – Mariner launched in 2003, just one year after Brilliance's 2002 debut. However, Mariner received a significant renovation in 2018, giving it updated facilities and modern touches.

Mariner takes the lead here with approximately 14% more dining venues than Brilliance. You'll find roughly 14 different dining options on Mariner compared to about 12 on Brilliance. Both ships feature popular Royal Caribbean staples like Chef's Table, Windjammer buffet, and Chops Grille steakhouse.
The bar scene also favors Mariner, which offers four additional bars compared to Brilliance. This translates to more spaces for evening entertainment and socializing throughout your cruise.
Entertainment Variety
Larger ships typically mean more entertainment options, and Mariner delivers on this front. The Voyager class design allows for more diverse activities and shows, though Brilliance certainly holds its own with quality entertainment programming.
Both ships feature theaters, but Mariner's larger size accommodates more elaborate productions and a wider variety of activities throughout the day.
What's the value proposition for each ship?
Mariner often gets tagged as one of Royal Caribbean's "best value" ships. It strikes an excellent balance between extensive amenities and reasonable pricing, especially compared to the newest mega-ships in the fleet.
Brilliance typically comes with lower base prices, partly due to its smaller size and fewer amenities. This makes it attractive for budget-conscious cruisers or those who prefer a less crowded environment.
Who Should Choose Which Ship?
Pick Mariner if you want maximum variety and don't mind larger crowds. Families with teens, groups with diverse interests, and first-time cruisers often gravitate toward Mariner's extensive offerings.
Choose Brilliance if you prefer a more relaxed pace and traditional cruise atmosphere. Couples, older travelers, and anyone seeking a less hectic vacation might find Brilliance more appealing.
How do the cabin experiences compare?
Both ships offer similar cabin categories, from interior rooms to suites. The main difference lies in the overall ship atmosphere rather than individual room quality.
Mariner's cabins benefit from the 2018 renovation, which updated furnishings and technology in many room categories. Brilliance maintains comfortable accommodations but may show its age in some details.
Suite Experiences
Both ships feature Royal Caribbean's signature suite amenities, including priority boarding and specialty dining perks. The suite experience remains consistently high across both vessels.
Which itineraries do these ships typically sail?
Both ships rotate through various regions depending on the season. Mariner often handles Caribbean routes from Florida ports, while Brilliance has sailed everywhere from the Caribbean to Alaska and Europe.
Your itinerary choice might actually determine which ship you sail rather than the other way around. Royal Caribbean assigns ships to routes based on capacity needs and seasonal demands.
Seasonal Considerations
Mariner's larger size makes it particularly well-suited for high-demand Caribbean routes during peak season. Brilliance's more manageable size allows it to access smaller ports that larger ships cannot visit.
What about onboard atmosphere and crowd levels?
Mariner definitely feels busier, especially around popular venues like the main dining room and pool deck. The ship's size helps distribute crowds somewhat, but you'll still encounter more people throughout your day.
Brilliance offers a more intimate experience where you might actually recognize fellow passengers by the end of your cruise. Lines tend to be shorter, and finding a quiet spot becomes easier.
Family vs. Adult-Friendly Environments
Both ships welcome families, but Mariner's extensive kids' facilities and teen areas make it particularly family-friendly. Brilliance works well for multigenerational groups who want to stay together without feeling overwhelmed by crowds.
The final choice often comes down to your cruising style: maximum variety and activity on Mariner, or a more relaxed, traditional experience on Brilliance.
