We are planning on using luggage tags as our escort cards and favor.  I will not personalize them with any of our wedding info (obviously). I plan on making business cards with my guests names to insert into the opening (so that it can be removed and used for it's rightful purpose.
I did find a few that I like that had options for personalization.  I was thinking of maybe using a quote like:
 “If you don't know where you're going, any road will take you there.”

George Harrisonor
“Remember that happiness is a way of travel -- not a destination”
I still am browsing quotes.  Is this a good idea?  I'm thinking a plain luggae tag will be more useful, and more likely to be used.  Just looking for feedback.  Also, if anyone knows of a place to get a nice looking tag on the cheap, let me know!
