I can see no reason why you can not renew your wedding vows on board my wife insists every time we cruise on Cunard that we do.the ship has a resident priest onboard so have a word with him ask at the pursers office they will put you in touch.
Thanks Christopher. Have you been able to do it as a single couple or has it been a "mass" renewal with other couples?
I have had both types the mass ones where pleasant about six couples’ only had to pay for the photographs’ for my silver anniversary I had a private one which was performed on the balcony of my stateroom in the Caribbean in the afternoon and in the evening we had a candlelight dinner on our balcony this was all arranged by our butler there was a fee for this. Your butler is a very useful person to have talk to him/her they have a wealth of experience to make your cruise an anniversary to remember.
Thanks so much for your help Christopher. I feel a lot happier that we will be able to renew our vows on board now. Thanks again.
