If you really want to get in the spirit, The Inn on Biltmore Estate is offering Dressing Downton hotel packages that include Afternoon Tea at the Inn and audio guides to Biltmore House.
There's also plenty of Downtown memorabilia in the gift shop should you wish to take home a memento. Downtown Abbey books, teas, hats, perfumes- the list goes on. I sampled some perfume and kept catching the delightful fragrance of "Daisy" on my wrist all afternoon.
This fashionable exhibition runs until May 25, 2015. Tickets may be purchased on line in advance or at the Biltmore Estate visitor center. Tours are more expensive on the day of and certain dates require reservations so it pays to plan ahead and visit the Biltmore website.
