I don't want to rain on anyone's parade but what's the deal about laminated tags? It is much easier and just as efficient to use any luggage tag (as easily recognizable or discreet as you wish) and insert your address and itinerary there. That method has the advantage of using less time and less resources (less plastic as well as less money) because it can be repeated over an over.
It is also more discreet because you can hide the info with the little flap most luggage tags have.
The method of attachment is the same, hence there is no advantage there, either.
So what's so great about laminated tags?
