We are going on a cruise to the Carribean for our honeymoon, but not going until 2 weeks after our wedding. I won't be changing my last name until after our honeymoon due to my passport having my maiden name on it. I was told we may want to take our marriage certificate with us just in case there is a problem getting onto the ship. I don't want to lose our marriage certificate, but not sure if they would accept a copy. Any thoughts?
