I have about half a dozen, mainly the resorts pins. It started by us receiving one for WL as we own a few points there. Can't say that I'm an avid collecter though.
I've got that pin too 1 of a set of 4 Lilo & Stitch ones, including a Stitch 'lightup' pin that flashes like he's firing his little ray gun, LOL. The only light-up pin I've ever bought - they are very cute
