I'm making them myself right now, am going to send out boarding pass save the dates/invites and direct people to a wedsite to RSVP. There will be info on the travel agent and where to go to book. Once I know who is coming and have details around welcome party/gathering, wedding location (ie, beach), time, etc... i'm making passport books for those that are coming and will probably send them out right before we go. If you need a template on the boarding passes, i can send you mine! I was hoping to mail them but looks like i might be hand delivering! lol
