Travelzoo once again offers an Adult Ticket to Downton Abbey: The Exhibition in New York, NY for $20. That's a $15 savings and tied with our mention from three weeks ago as the best deal we could find for this admission. This replica of the Crawley family estate spans three floors. Originally expected to close on April 2, Downton Abbey: The Exhibition has been extended until the end of the month. Book this travel deal by April 30 for entry through the same date.
