Mine is for a cruise wedding but it may help you:
Dear Family and Friends,
We thank you so much for taking the time out of your schedules to join in on our wedding ceremony, whether it be for the day or the week of festivities we are very pleased that you are able to join us. We have guests joining us not only from all over the country but from Ireland and Australia as well. My wish is that everyone takes the time to meet each other and have a relaxing and enjoyable vacation of your own. We enjoy watching other have fun as much as we enjoy having fun ourselves so a cruise wedding seemed to fit right in with our idea of a perfect wedding ceremony. We look forward to seeing you at our welcome dinner, for transportation to the port, and at the wedding. Please take the time to enjoy the buffet on the Lido deck before the wedding ceremony begins but save room for the reception, open bar, and cake!
Love,
