Party at the Castle
From the venue:
This magical evening is a must-attend for adults who really wanted to get their letter via Owl Post. Feast in the Great Hall, take home creations from Potions and Herbology, and explore the decorated castle with the Marauder's Map. You can test your mettle with a scavenger hunt and a trivia game. A number of Divination appointments will also be available, and everyone is encouraged to participate in the costume contest (though Muggle attire is also acceptable).
