Has anyone used wedding cruise or any experience about wedding cruise? My brother would like to get married in an island that includes a 5-6 night cruise to the Caribbean area.

Hi. I have not experienced a cruise wedding, but I am an experienced cruiser.

The first thing that you need to know is that Princess Cruise Line is the only one that will marry you "at sea." All other lines (Royal Caribbean, Carnival, etc.) you need to be married before the ship sails or when it is docked in port (at one of the destinations on your itinerary.)

My friend was able to experience cruise wedding and it was really unforgettable as I witnessed how happy she was during that moment.

If you want to have a nice wedding with beautiful service i would reccommend royal carribean. trust me the experience is so much better.
Also when you marry on cruises, you can't bring your own bouque of real flowers, you either have to buy them from the ship or bring fake ones.
