I figured this deserved a thread here in the events space! Generally every Sunday there are pin traders gathered in the picnic area outside the theme parks (but still on property) or in Frontierland inside Disneyland park. Since Thursday is new pin release day, they can be found usually in Frontierland as well. I can't always guarantee which forum members may or may not be there, nor how many, but there should be at least some people trading. Here are some details and even maps to give everyone a general idea of the areas, I took these as screen shots from the Disneyland app! Picnic Area. This area is obscured by tall hedges, but is near the TRAM drop off. It's also near the Hagen Daaz stand. There are restrooms just outside the hedge next to the locker area. There are also lockers inside this picnic area. This area has lots of tables and lots of shady spots! This area is OUTSIDE of both theme parks, but nearish to Disneyland's entrance. No park admission required! Frontierland. This area is near the Westward Ho pin store. There are a few benches, but people usually display their pins on them, or even on the tops of trash cans. There are generally no tables here, and you likely have to stand next to your pins. There is one barrel table outside the door of the bigger shop Pioneer Mercantile, just across from Westward Ho, where you may find several people gathered around. This location is INSIDE of Disneyland park, and thus requires park admission. These are currently the only two areas I know there's for sure trading going on. I don't know if people meet much in DTD at that pin shop anymore. Some pin traders still meet in DCA near Goofy's Sky School early on Sunday morning, but I've been told they have to clear out of there before noon, and if there are also too many people they will be asked to leave. Disney managers do not really want people trading over there anymore, because it takes away from tables for guests trying to eat at the restaurants.
