Chic Luggage Tag Wedding Favors

I'm kind of obsessing over the amazing luggage tags as wedding favors for guests from Of The Fountain.  I think they would make such fabulous favors, escort card holders or even bridesmaid or groomsmen gifts.  They have such an expensive and timeless feel to them.  Rather than write "Emma & Jake's Wedding" on them so no one can use them, how about personalizing them with each guests name, or going with a saying like "Not all those who wander are lost" or how about "It's not the destination, it's the journey" which is kind of a cool sentiment about love and marriage in general. 

 These (above) would be a great wedding gift for the bride & groom to send them off on their honeymoon.

And these are super cool that mark the longitude and latitude (again of the wedding location for a bride & groom gift?).
