If you are unable to attend these alternate viewing hours and would like a refund, please send your ticket(s) to: National Geographic, 1145 17th St NW, Washington DC, 20036, Attn: Ticket Office. Although the Museum was open, road and transit conditions made it difficult for many ticketholders to travel to the Museum on the following dates: February 5, 8, 9, and 10. The Museum will also honor these tickets during the alternate viewing hours listed above. Updates for the rest of the week will be posted as soon as possible.
