We was going to renew our vows on board one of the Princess ships next May 2010 but as they do not do them as a separate ceremony and only do them in groups we was not keen. I have also been told that they do them in a bar or similar. You may be lucky and be the only ones for that day but I was also told that they try and do them altogether on the same day. We have now arranged to renew our vows in Florida at the Wedding Chapel on International drive the week before. And they are cheaper than Princess Cruises.
