Absolutely, you need to grab some chips.
I covered mine (both sides) with clear contact paper, the used a hole punch to make a hanging spot in one corner. I used some extra silky cord (from a craft store) to tie through a button hole on my shirt, and pieces of pipe cleaner (chenille stems) to fasten them to my camera bag and waist pack.
Some people put them in the windows/doors of their resort rooms, or attach them to strollers. It was fun spotting them around the parks each day. I didn't see a lot of them, but I did meet someone in Crystal Palace at dinner one night.
Just a little extra magic from DIS.
