We did this inside our passport invites.....
"The journey of our love began on the beaches of the Atlantic Ocean. We find it fitting to have our wedding there as well. We look forward to sharing our day with those who can join us. It is our hope that you hear the sound of the ocean as loudly as we hear wedding bells.
Although it would be fantastic to have all of our loved ones there as witnesses, we understand that limitations exist. For those who are unable to join us, it is our hope that you look south on our special day and say a prayer, wishing us well as we begin our new lives together."
