Well, I see a few new names here.

Hi, and welcome to the Collectors Board.
Check my signature for links to good places to find general information on pin trading at WDW, specifically the Collectors Board FAQ and the Pin Trading Etiquette area on wdwinfo.com. Rules regarding trading with CMs can be found in both places.
If you're looking strictly for CM trading, you can find lanyards all over the place at WDW -- the parks, the resorts, the shops at DTD. If you're looking for other collectors to trade with, the main pin stations -- the hat at MGM, Pin Central at Epcot, Expo Hall at MK, and the pin cart near Island Mercantile -- are popular gathering places. There is also Disney Pin Traders at DTD, right across from Once Upon A Toy.
I always recommend this -- go see Scoop's seminar at Expo Hall in MK. Last I heard it was held Sunday thru Thursday at 1:00 PM, but you might want to double-check with anyone at Expo Hall.
The Saturday night pin meet at the Poly is not an official Disney-sponsored meet, but it's still a great meet. Disney does sponsor the pin meets at the Contemporary on Friday nights, at the All Star Sports on Thursday nights, and at the Boardwalk on Sunday nights.
Donald Duck 57, did you have a bad experience with a rude guest? If so, don't let that discourage you from displaying your traders.
