NCL is the original gay friendly cruise line. They created the famous Friends of Dorothy socials and have been known to throw passengers who hassle gays in the brig...i.e. thrown off at next port. I know that they would arrange a gay wedding in one of their entertainment venues. ie. at top of ship. They do not throw gay or straight weddings in all access public areas, i.e lobby or top outside decks. Call them and ask for details, This Gay cruiser loves and respects NCL.
