My son loves pin trading when we go to Disneyland or the Walt Disney World Resort.
Here's a great how to from the "official source"
What is Disney Pin Trading?
Disney Pin Trading is an exciting, interactive experience where our Guests can trade Disney pins with our Disney Cast Members and other Guests. It's fun for the whole family and CREATES cherished "pin pals" to last a lifetime! Start a new collection or exchange pins for the ones you've always wanted.
How can I experience the magic?
It's simple and fun! Just visit Walt Disney World, the Disneyland Resort or Disneyland Paris, locate a Cast Member wearing a lanyard with Disney pins and find a pin you'd like. Then present another Disney pin to the Cast Member in trade. Bringing home the magic is that simple. Plus, we have some quick and easy guidelines to help you trade at each park.
"The Trading Tradition"
Disney has always offered collectible Disney pins in each of its parks, but with the kickoff of the Millennium Celebration in October 1999 at Walt Disney World, we began a new tradition of Disney Pin Trading. Now thousands of Guests trade each day with our Cast Members as well as other Guests throughout the parks and resorts. Like sharing Disney stories with your children and grandchildren, sharing pins is a delightful tradition for each generation. Mark the beginning of the century with pins you love and memories you'll treasure.
Which ones should I collect or trade?
The fun of Disney Pin Trading is in the amazing variety. Find YOUR FAVORITE pins to personalize your Disney experience. Guests of all ages can hunt for favorite characters, attractions and features. Whether it's the Little Mermaid or Mickey Mouse you seek, pin hunting is guaranteed to add thrills to your Disney adventure. Go find the pins you want and make some new friends! It is all up to you! Have fun! Disney Pin Trading is a great way to share the magic and bring home wonderful Disney memories.
I have a special pin starter set and lanyard as a thank you for booking your next Disney vacation with Northwest Family Vacations between now and the end of the year too!
