Each year, the pin traders get a separate ticketed breakfast event that gets them in the doors and trading early. This year, Vinylmation will have one as well. It is called the Villainous Vinylmation Breakfast and is a separate ticket on top of your event and park tickets. More info on pricing to come in the next few days.
The Disney Parks Blog also mentioned all the merchandise that will be at the event. It is much more than vinyl and pins this year. Expect to see: Event logo tees, a baseball hat, D-Tech phone cases, individual pins, jumbo pins, pin sets, original and limited edition artwork, sculptures, Vinylmation (even a few custom pieces), as well as a “lucky” ear hat.
