Destination wedding vs. flower preservation

Hi all! I’m having a destination wedding in July, and I’ll be in Costa Rica for a week after our wedding for our honeymoon. I really really want to be able to bring back/preserve pieces of my bouquet to bring back home with me. (I already researched... as long as the plants aren’t “living” with roots, it’s okay) but I’m having a hard time coming up with ideas on how to get the florals back. I’m thinking about bringing a book and pressing the flowers. But does anyone else have any ideas on what to do?
