When we were there in October there was a Descendants dance party at the Halloween party, but that was it. However, we ate at Artists Point and and my daughter wore her Evie costume(the evil queen is Evie’s mother). The queen played into it and made a big thing about her “looking familiar” and pointing out things on her costume that matched the queen. My daughter was thrilled! It was the best character interaction of our trip. It’s obviously not guaranteed, but if she likes Evie she might get a kick out of meeting her “mother.”
