Whether or not a cruise line is legally able to perform a wedding at sea depends on the laws of where the ship is flagged. For example, 13 Princess ships are flagged in Bermuda, so all of those ships’ captains are vested to perform legal ceremonies during cruises. Most of the ships have wedding chapels on board (and those that don’t have them in the library), as well as onboard florists who can design arrangements to suit your specifications. Princess even offers registries (with an easy-to- use app) to make it simple for guests to contribute to your honeymoon, and they can buy you everything from Champagne and specialty dinners to shore excursions. And, just because you’re at sea doesn’t mean you shouldn’t ask about chocolate fountains and handwritten place cards; most lines can handle the same sort of requests you would make on land. Crystal Cruises will even ask the onboard chefs to prepare your family recipes for the dinner reception.
