Parking for Christmas at the Mansions is free on the grounds of David Davis Mansion at 1000 Monroe Drive, and at Ewing Manor in the parking lot across the street at St. John's Lutheran Church on the corner of East Emerson Street and Towanda Avenue.
This event is a self-driving tour. Do it at your own pace and see whichever home you want to see first. Just be sure to leave enough time to see both places. Allow at least one to one-and-a-half hours at each location.
