We were invited to "crash" the wedding of some people we met via Carnival Connections who were "eloping" with a Carnival wedding cruise on Liberty this past May 4th because they could only get married onboard unless they had a minimum of 20. The ceremony was perfect and reception just right. The bride and groom were the best. Although there were just the bride and groom, the best man and his wife, another couple they were friends with and another military friend, when you added in our group of 10 women of all ages from Illinois, Texas and New Jersey, the Bride and Groom couldn't have been happier. Carnival did a wonderful job making sure everything went off just as planned.
We were allowed to embark before everyone else, had the festivities, had time to change and were out on deck in time to enjoy sail away out of Port Everglades.....
I would not suggest a wedding onboard if you're going to have more than 30 even though they can accommodate larger parties. I think the smaller parties is what makes the cruise ship wedding special...
By the way, the dvd, pictures, cake, etc. that the wedding couple received as part of their package were beautiful.
