You might want to try posting this on the collector's board. You will get a better response (or maybe one of the mod's can move the thread).
I have 3 lanyards. One of them, a red one I got from the DC for being a "best guest" has a best guest medalion on the end. The black WDW I bought about 3 or 4 years ago had a plastic card on the end, which I removed and put one of those plastic holders - that will hold my id, ticket or whatever item like that in there. I do have a plain black one that I got from the whatwouldwaltdo.com web site. That one has a WWWD medalion on the end of it. I think the red and black ones have a velcro tab at the bottom, where the medalions are. The WDW one has it at the back of the neck. I don't have a problem with wearing them around the parks, but would take it off for certain rides (such as TOT or RNRC).
Hope this helps! You can get more help over at the collector's board.
