Our luggage is pretty standard and so a little hard to pick out from the hundreds of other bags on the carousel. So we always try to put something on the bag that will stand out. For us, something Disney does the trick:
Mickey is pretty easy to spot
Minnie might stand out just a little bit more!
This last trip we used some personalized luggage tags that friends made up for us, but supplemented them with these high-profile and bright luggage tags, just to make it that much easier to find our luggage.
We bought these at The World of Disney at Downtown Disney.
