I think pin trading at DLR is pretty popular, but because the resort is smaller overall, it feels like there are less pin trading opportunities. On a park-to-park level, I think it's pretty comparable. I have noticed that at DLR, there does seem to be fewer CMs wearing lanyards, but many the stores have a Mickey-head shaped pin board at the register (or somewhere in the store). I know I've seen a board in at least one shop in each land, except maybe Fantasyland. I've traded with boards at the 20th Century Music Company (pin shop) and the Emporium on Main Street, Star Command and Star Tours in TL, the pin shop and Mercantile in Frontierland, the shop across from the Jungle Cruise in AL, the Minnie Shop in NOS, the plush toy room in the Winnie the Pooh shop in Critter Country, and the Gag Factory in Toon Town in DL. I've seen pin boards or similiar in Elias & Co and the pin shop on BVS, at Clarabelle's (a rare one at a food place), Grizzly River Outfitters, the Ariel store, the pin shop on Paradise Pier, all three shops in Carsland, the ToT shop, and the Art of Disney in DCA. Frontierland also has a larger board (sometimes a regular board, sometimes a wheel) that is usually out over by the Frontierland Mercantile. I've also seen the Mickey-head board or similar at WoD (usually at the entrance furthest from the parks), the pin shop and D-Street in DTD and at the Harbor Side Information kiosk. Most times, I've seen the boards out in the open, except the Emporium one that they seem to put away occasionally.
