Frequenty Asked Questions
What are the main differences between Explorer of the Seas and Mariner of the Seas?
Both ships belong to Royal Caribbean's Voyager Class, but they're not exactly twins. Mariner of the Seas edges out Explorer with slightly more space—139,863 gross tons versus 137,308 tons. That translates to room for about 60 more passengers when cabins are double-occupied.
The timeline tells an interesting story. Explorer launched in 2000 as one of the original Voyager Class ships, while Mariner followed three years later in 2003. However, their renovation schedules flipped this timeline—Mariner got its major refresh in 2018, but Explorer received the more recent 2023 renovation.
Size and Capacity Breakdown
Explorer accommodates 3,286 passengers at double occupancy with a crew of 1,185. Mariner bumps those numbers up to 3,344 passengers and 1,200 crew members. The passenger-to-crew ratio stays identical at 2.8 for both ships, so service levels remain consistent.
Which ship offers better dining options?
Mariner takes the lead here with roughly 22% more dining venues than Explorer. This means more variety for your taste buds and potentially shorter wait times during peak dining hours.
Both ships feature the standard Royal Caribbean dining options you'd expect—main dining room, specialty restaurants, casual eateries, and room service. Mariner's advantage comes from additional venues added during its 2018 Royal Amplification upgrade.
The extra dining choices on Mariner range from quick bites to specialty cuisine, giving you more flexibility whether you're craving a late-night snack or want to try something completely different from the main dining room menu.
What entertainment and activities set these ships apart?
Both ships share classic Voyager Class features that made this ship class famous. You'll find the FlowRider surf simulator, rock climbing walls, The Perfect Storm waterslides, and ice-skating shows on both vessels.
Mariner gained some exclusive advantages through its 2018 Royal Amplification upgrade. The ship added laser tag, an escape room, and the Sky Pad (though this feature is scheduled for removal). These additions give Mariner a slight edge for thrill-seekers and families with older kids.
Unique Features by Ship

- Adults-only Solarium

- Integrated balcony design
Mariner of the Seas:
- Laser tag arena
- Escape room experience

How do the cabin designs differ between the two ships?
Here's where architecture gets interesting. The balcony designs follow different approaches—Explorer integrates its balconies within the ship's superstructure, while Mariner's balconies extend outward from the hull.
This difference affects more than just aesthetics. Mariner's protruding balconies often provide better views and feel more spacious since they extend beyond the ship's main structure. Explorer's integrated design creates a sleeker profile but may feel slightly more enclosed.
Both ships offer similar cabin categories—interior, ocean view, balcony, and suite options. The layouts and amenities within each category remain largely comparable, with minor variations based on each ship's specific design.
Which ship provides better value for your cruise?
The answer depends on what matters most for your vacation style. Explorer's 2023 renovation means you'll experience fresher decor and updated facilities. Everything feels newer and more modern compared to Mariner's 2018 refresh.
Mariner compensates with more dining variety and additional entertainment options. If you're someone who likes trying different restaurants or needs extra activities to keep everyone happy, Mariner's expanded offerings provide better value.
Consider These Factors:
Choose Explorer if you want:
- The most recently updated facilities
- A slightly more intimate feel (fewer passengers)
- Classic Voyager Class experience with modern touches
Choose Mariner if you prefer:
- Maximum dining variety
- Additional entertainment options
- Slightly more space and amenities
Are there any significant differences in service quality?
Service quality remains remarkably consistent between both ships. The identical passenger-to-crew ratios mean you'll experience similar attention levels regardless of which vessel you choose.
Both ships maintain Royal Caribbean's service standards with professional staff, efficient operations, and responsive guest services. The crew training and service protocols follow company-wide standards rather than ship-specific approaches.
The main service difference comes from facility age and layout. Explorer's recent renovation means newer equipment in restaurants, updated cabin amenities, and refreshed public spaces that can enhance the overall service experience.
Which itineraries do these ships typically sail?
Both ships rotate between Caribbean and seasonal deployments, though their specific itineraries change based on Royal Caribbean's fleet positioning needs.
Explorer typically focuses on Caribbean routes from Florida ports, offering 7-night Eastern and Western Caribbean itineraries. The ship occasionally repositions for seasonal deployments to other regions.
Mariner follows similar patterns but sometimes ventures into different markets based on demand and fleet requirements. Neither ship is locked into permanent routes, so your choice shouldn't be based solely on current itinerary options since these change seasonally.
Check Royal Caribbean's website for current deployment schedules, as both ships may sail similar routes depending on when you're planning to cruise.
