Picture it: golden light on the water, a breeze off the bow, and the people you love most gathered on a ship that’s about to carry all of you somewhere beautiful. A wedding at sea pairs the romance of a destination wedding with the ease of a cruise. Your venue, dinner, entertainment and honeymoon all come with you on one ship.

It also has more moving parts than most couples expect. This guide covers how cruise weddings work, the timeline, what to know about guests, and where we come in.

Quick note: We book the cruise line’s wedding package. We aren’t the wedding planner, and the cruise line runs the ceremony itself.

How a cruise wedding works

Cruise lines that offer weddings typically sell them as packages you add to a cruise reservation. Depending on the line, the ship and the itinerary, you can usually choose from three settings:

At sea, with the ship in international waters, on select sailings and ships.
In port before you sail (an “embarkation” wedding), with your guests coming aboard for the ceremony.
At a destination, on a beach or at a venue at a port of call.

Here’s one example. Royal Caribbean’s wedding FAQ says the Captain can perform your ceremony once the ship is in international waters, and that the marriage is recognized in The Bahamas, where its ships are registered. It also tells couples to check with their local authorities about recognition at home. For ceremonies in U.S. ports, it says a notary public or a non-denominational officiant presides. (Not affiliated with or endorsed by Royal Caribbean.)

Every line sets its own rules, so the first thing we confirm for you is what’s offered on the exact ship and sailing you love.

At-sea ceremonies are run by the cruise line on select sailings and ships; legal requirements, fees and recognition vary. Ask us for current details.

The timeline: start earlier than you think

This is where couples get caught out. A wedding at sea isn’t something you add a few weeks before sailing.

Book well ahead. Royal Caribbean, for example, says all weddings at sea must be booked at least 90 days before sailing and strongly encourages booking as far ahead as possible.
Paperwork takes time. The same FAQ calls the Bahamian maritime marriage license process “complex” and says it needs at least 90 days to process. Its wedding team helps couples with it.
Details have deadlines. For example, Royal Caribbean asks for ceremony song choices at least 21 days before sailing.
Holidays may cost more. The line notes additional fees on some holidays and at its private destinations.

Our advice is to talk to us about a wedding cruise as soon as you have a rough season in mind. Ceremony venues and officiants have limited availability, and the cruise line confirms your date based on them.

Who can say “I do” at sea

Not every ceremony can happen at sea. Royal Caribbean says same-sex legal weddings can’t be performed at sea, because its ships are registered in The Bahamas. The line offers symbolic same-sex ceremonies at sea and legal same-sex weddings ashore, in U.S. ports and in ports abroad where legally permissible. Other lines have their own rules. Tell us what matters most to you, and we’ll find a sailing and setting that fits.

Bringing your guests along

The guest experience is the heart of a wedding cruise, and the reason so many couples choose one. Your loved ones don’t just attend a ceremony. They get a vacation with you.

Guest limits depend on the package and the venue. Royal Caribbean, for example, says the maximum number of guests for a shipboard ceremony depends on the package you pick and the venue’s capacity.

Everyone books a cabin. Guests who sail with you need their own staterooms. Each guest pays for their own cabin, and we keep the whole group organized: who’s in which room, who’s flying in from where, and who still needs to send documents.

Getting there matters. Wedding parties often need to be at the pier at a set time. For first-day ceremonies, Royal Caribbean gives wedding parties priority boarding and asks them to arrive at a specified time. That makes flying in the morning of the cruise extra risky. Arrive a day early, and we can book a hotel the night before for you and your guests (see our cruise port hotel guides).

Documents. Remind guests early about passports and IDs. On a closed-loop cruise that starts and ends at the same U.S. port, U.S. Customs and Border Protection says U.S. citizens can re-enter with a birth certificate and government-issued photo ID. Ports you visit may still require a passport, and for your own marriage paperwork you’ll want your documents in order well before the 90-day window.

Paying for the wedding package

Here’s how one line handles it. Royal Caribbean says the wedding package is applied to your cruise reservation and follows that reservation’s payment schedule. You’ll pay the cruise line directly, as with any cruise booking. Add-ons are typically chosen around 45 days before sailing. Ask us to walk you through the schedule on your sailing.

Little details that make it magic

Choose your setting: a chapel at sea, an open deck at sunset, or a beach at a port of call.
Plan for weather. For outdoor ceremonies, Royal Caribbean says alternate arrangements are made at the coordinator’s discretion if the weather turns.
Ask before you pack decorations. Decorations you bring aboard are subject to the cruise line’s approval.
Make it a honeymoon too. Once the guests head to dinner, you’re already on your honeymoon. For more ideas, see our honeymoon cruise ideas and celebrations at sea.

Where we come in

You tell us what you want, and we handle the research, the booking and the details, so you don’t have to.

For a wedding cruise, that means we:

Compare ships and sailings that offer the kind of ceremony you want.
Book the cruise line’s wedding package with your cruise.
Book cabins for you and your guests and keep the whole group organized.
Book a hotel the night before so nobody misses the ship.
Keep you on top of the cruise line’s deadlines.

And there’s no planning fee on your cruise.
