We just returned from a week at WDW, and found a few good pins on the lanyards. We were at AK Wednesday, and the CM lanyards had just been refreshed with some California pins. Other than that, we found the pins on the lanyards very repetitive, although I did find a PI Happy New Year 2001 pin (CM, I think) that I haven't been able to locate on Pinpics and an AK Lodge CM pin ( these were on lanyards at DTD, surprisingly enough).
I took DS pins along for traders, and the CM were always delighted to have something different on their lanyards when we traded. Some people wanted to trade for DS pins they had not seen or had the chance to get.
So, have fun, and good luck with your trading. Wish we were back in Florida. (It's 25 degrees here in Maine this morning!)
