I saw a great program on the Travel Channel about some wedding planners in Grand Cayman- it was focused on a company called CelebrationsLtd and they really put on a nice wedding. I wish you could access the video..... Have a look at their website.
BTW- you cannot get married at sea- you have to get married at embarkation, or at one of the places you visit.

Thanks Emdia43

I will try and follow that up.

Yes, having to technically get married in port first, was one of the reasons I was having second thoughts about the cruise ship wedding ...not very romantic.

You most certainly can get married at sea. My son did 3 years ago onboard the Caribbean Princess ! regards Denny

You can get married at sea, yes, but the commonly-held view that ship's captains are automatically entitled to perform weddings is not true.

Generally the only circumstances where a ship's captain can perform a wedding would be where the captain is a person who would be qualified to do so anyway, such as a minister of religion or a licenced marriage celebrant. The right is not ex officio for being a captain.

There is a specific law in Bermuda which recognises any marriage performed at sea on a Bermudan-registered ship by a person licenced to perform them, and so captains of some Bermudan-registered cruise ships have applied for and been granted such a licence. Again though, it's not an automatic right of any captain of a Bermudan-registered ship.

But she's not asking about Princess cruises she is asking about Disney...
Disney is Bahamas registered. As far as I am aware that still takes a Florida Marriage License.... the legal portion of the wedding is conducted in the terminal before you embark and then you can have a wedding ceremony onboard.
Another thing to consider with an island wedding on a cruise is- what happens if bad weather cancels that port of call? which does happen with Grand Cayman.. I don't want to put a damper on your plans,but you need to consider what if....
