No trust me, they will stop you. They have stopped many a people in the parks.
They have such strict rules regarding weddings. Customer service is excellent but they will not take the day away from a paying bride and let an unofficial wedding happen.
I have dealt with Disney Fairy Tale weddings for 2 occasions.
They only allow 2 to 3 weddings per cruise depending on how many sea days and the length of the cruise. One wedding on
Castaway Cay per cruise. They make each wedding custom to one bride. They will not allow 2 brides to see each other, they make you feel that you are the only bride that day. You pay for that service and they make sure you get it. I had a vow renewal in 2012 on The Magic and we chose to do it onboard on a sea day. I was the only one that day and then there was one CC wedding on the Friday.
Go to the wedding boards on this forum and ask, they will tell you.
I am not trying to make trouble, I just know how Disney is with their weddings. They will stop you on CC if you try to have a beach wedding you didn't plan and pay for thru Disney.
Their Best service is always given as we know. But if you try to pull of an unofficial wedding with things you suggested they will stop you.
Lurkyloo, who is on this board was married in Disney the same month my daughter had her Disney wedding wanted to meet up with a bride getting married the same day as her had to get all kinds of permission for them to be seen together in their wedding attire.
Disney takes their weddings seriously.
