I’ve only traded at a few resorts but my favorite has to be Port Orleans – French Quarter. It’s probably not the best out of all the resorts, but I managed to find some awesome (and real!) pins on some very helpful cast members’ lanyards. 🙂
In California, my favorite place to pin trade is at the Paradise Pier Hotel. Also, any of the bell hops! They always have some brand spankin’ new Hidden Mickey pins 🙂 I haven’t made it to WDW yet, but I’m so excited to here the best spots to pin trade for the future.
