Santa Visits the Rosen House: Jolly Saint Nick comes to fill The Rosen House with holiday cheer. The little ones will be in for an adventure with I Spy a Santa or Two in The Music Room, followed by a 30-minute concert of favorite holiday songs when Santa Claus will appear to delight the whole family. Santa’s favorite snack — milk and cookies — will be served in the cloisters. Bring your cameras and begin the festive season with joy!
