Hello! We are getting married on a yacht and the yacht is leaving the dock at 6:00pm SHARP! If guests are not in a hotel lobby 10 minutes before departure, then they will not be allowed on the boat.. Could you give me any suggestions on how to let people know? Is the invitation not the place to say that? Word of mouth? Wedding website (but not everyone has internet). We are also restricted on the # of people (coast guard regulations), so the yacht company suggested saying along the lines of "Due to coast guard regulations the request of a number attending is greatly appreciated" on the response card or something like that, I don't have the paper in front of me... Is that rude? I'm stuck.. Thank you for any help!
