we would like to get married on a vach at a port stop
Hello jdfree. Welcome to cruise-chat. What is a "vach"? Do you mean beach? Lots of choices out there, but these diminish if you only want to do a 3-5 day cruise. Beach wedding are popular on St. Thomas but you'd need a 7-day cruise to go there.
Also - I deleted your other post since it was a duplicate message. We ask that members don't post the same message multiple times. It just confuses things as far as responses.
