How do you surprise someone with a holiday?

It's straight forward - take a box and fill it with miniature boxes made from photos of the holiday destination, hiding the tickets and reservations inside. Replicate a beach in glitter and pop messages-in-bottles along the shoreline with more pictures of things they'll see. Add an 'Airbnb' branded box with pictures of your Airbnb in because you/they are obsessed with Airbnb. Give it to them and let 'em figure it out.
