Your beach wedding invitations should include all of the same information a regular invite would. Things like the date, time, location information for the ceremony and reception (address, city, country, etc.), RSVP information, and wedding website info.    In addition, include helpful instructions for booking their trip and information about the resort/hotel where you've reserved rooms.  If you're hosting a destination wedding, we strongly recommend that you create a wedding website in addition to sending out paper communications. This way, you can coordinate all of your pre-wedding events (like rehearsal dinners, etc.) and coordinate closely with your guests in one easy place.  (P.S. - Minted makes this easy with free wedding websites that match your invitations and act as the hub for your guests to find all of your wedding deets!)
