We'll be celebrating our ten year wedding anniversary on this cruise! What's the possibility of the Captain officiating a vow renewal ceremony?

It is rare to impossible to get the Captains to officiate these days. RCCL either doesn't allow it, or strongly discourages it. And that has much to do with the desire to prevent folks from rushing to get married and such during a cruise. Likewise, it drives more folks to the official services they offer.

I am in such dire need of a cruise, I envy your trip!
