I think our elected representatives will decide that failing to remove health insurance for 30 million US citizens is not a good enough reason to shut the US Government. I do NOT think the government is going to shut down. Call me optimistic. Can you wait a few days to see what happens??
1) Social Security checks for seniors, people alamo rental car las vegas with disabilities and survivors would still go out. But new Social Security applications will likely not be processed during any shutdown, as during in the previous shutdowns.
8) SBA approval of applications for business alamo rental car las vegas loan guarantees and direct loans to small businesses would likely cease, impacting the engines alamo rental car las vegas of our economy and potentially slowing the economic recovery.
You're best off watching the news and listening to the expert political commentators on this one. They would have a much better alamo rental car las vegas sense of whether alamo rental car las vegas the government will shut down than the average person on here.
It's impossible to know this until next Monday, and even then it's impossible to know how long any closure might last. But generally tourist attractions are expendable and will be closed, as will public buildings, during any government shut-down.
You may want to wait until Monday and see. If you are driving, a last-minute change is fairly easy. If flying, not so much since the government shutdown would not affect air service. But if you have nonrefundable hotel reservations, I don't know if you'd get your money back ... perhaps ... you'd need to contact the hotel directly.
The Society of Cincinnati gives free tours of its headquarters, Anderson House, which is one of the showcases of the Guilded Age in Washington. The house is in Dupont Circle. Check www.societyofthecincinnati.org
Outside the city, Mount Vernon in nearby Alexandria and the National Aquarium in Baltimore are privately operated and would remain open. There are other museums and activities in Baltimore or perhaps even Williamsburg or Richmond, Virginia could be options. I'm sure other posters can chime-in with their favorite non-federal Washington attractions.
I believe also the Woodrow Wilson house museum is not a federal museum. He was a very interesting person and the museum in his house if very good. But I just checked their website and it is closed alamo rental car las vegas for maintenance for most of October.
There is also the Newseum, and Hillwood. Dukey, most of the things we are mentioning as alternatives ARE in DC proper. If the trip can't be postponed, it's more helpful to offer good options than to snark.
Thank you for all your input. We already have airline tickets, so we will probably alamo rental car las vegas go regardless, it may be too expensive to change cities. Thanks for all the "non government" museum recommendations. We will have fun no matter what we do!
