How to Find a Less Crowded Cruise Ship
Use space ratio when you want more ship per person. It is gross tonnage divided by guests at double occupancy, and it is not a headcount of the pool on a holiday week.

A less crowded feel starts with space ratio and guest count, not with a slogan. Among non-expedition ocean ships below, the highest recorded space ratio is Seven Seas Grandeur at 74.4. Expedition ship Viking Octantis lists 79.8. Carnival Celebration lists 34.1. None of these numbers is a promise about your embarkation day.

Read the ratio with the guest count
- Seven Seas Grandeur pairs space ratio 74.4 with 746 guests. Icon of the Seas pairs 44.7 with 5,610 guests. Both can be the right ship for different weeks.
- Crew ratio is guests per crew member at double occupancy, from the same hull numbers. Grandeur lists 1.36. Celebration lists 3.10. A lower crew ratio is more crew per guest, not a service review.
- Viking Octantis is an expedition ship: 30,150 gross tons, 378 guests, space ratio 79.8. Viking Saturn is an ocean ship: 47,842 gross tons, 930 guests, space ratio 51.4. Do not average them.
- Disney Adventure lists space ratio 34.7 and 6,000 guests. Disney Treasure lists 41.5 and 3,466 guests. The line is not one density.
- A sailing can still be full. Occupancy on a date is Not listed.
- If the ratio is blank, leave it blank. Princess and Seabourn are Not listed, so they do not go on this ladder.
Ratios are generated from gross tonnage, double-occupancy guests and crew. A null input stays Not listed.
Frequently asked questions
Does a higher space ratio mean a quiet ship?
It means more tonnage per double-occupancy guest. It does not count people on a particular afternoon.
Is the smallest guest count always the calmest?
No. Read it with the ratio. Viking Octantis lists 378 guests and space ratio 79.8. A ship with few guests and a low ratio would be a different story, and that pair is not this table.
Why is crew ratio here?
It is the other recorded density figure. It is guests per crew member, not a review score.
Can I use this for a river ship?
River space ratios are often Not listed because gross tonnage is Not listed. Use passenger and crew counts on the river guides instead.
