How many cabins make a group cruise?

Most cruise lines treat 8 or more cabins as a group, and most count it as 16 guests sharing two to a cabin. That's the usual starting point for group pricing, group amenities and organizer credits.

What counts toward the minimum

The cabin count is what matters, not just the headcount. Eight cabins with two guests each meets the usual minimum. Six cabins with three guests each, 18 people, often doesn't, because it's still only six cabins.

A few other details that come up:

• Solo travelers occupy a cabin on their own and count as one cabin, but they usually pay a single supplement.
• Children in a parent's cabin count as guests, not extra cabins.
• Every cabin has to sail on the same ship and date to count as one group.

River cruises are different

River ships are much smaller, so river lines often start group terms at about 10 guests rather than 8 cabins. If your group is between 10 and 15 people, a river cruise may get you group terms an ocean line wouldn't.

What if your group is smaller?

Under eight cabins you can still sail together; you just book as individuals on the same sailing. You won't get group amenities, but nothing stops you from planning a dinner or excursion together. Some groups start small, book a few cabins, and pick up more members once the trip is announced. Many lines let you add cabins to a group until shortly before final payment, as long as space is available.

Why the number matters to the organizer

Group size drives three things:

• Group terms. Deposits and release dates for groups are usually more flexible than for individual bookings.
• Extras. Larger groups have a better chance at a private reception, reserved dining or a meeting room.
• Organizer credits. Many lines give the organizer a credit once the group passes a set number of paying guests. See how organizer credits work.

How to estimate your number before you ask

Count the members who said yes at your last trip or event, then assume about a third of interested members will book. If 45 people say they're interested, plan for about 15 travelers, or 8 cabins. A quick member survey gets you a better answer than a show of hands. When you're ready, send us your group's details and we'll tell you how the numbers work on the sailings you're considering.
