Gryffindor, Slytherin and all the rest are invited to an after-hours Yule Ball filled with games, crafts, and activities for all ages. Shop at Diagon Alley, wander the path of the Forbidden Forest, try some Butterbeer in the Great Hall, and find the horcrux for a second entry into the drawing for the door prize. Children, make sure to stop by Ollivander’s to choose your wand (or be chosen by it).
