Smithsonian Castle

We really enjoyed the tour. Everyone at Union Station was extremely helpful. Things can get confusing between catching the blue line, but all you have to do is talk to the staff on the bus. They do their best to make it easy for everyone. The only suggestions for improvement. The web site says hours are until 4 but the last busses run until 5. I would also include an on line map with the on line vouchers and make it clear where you need to pick up the bus. You have to show your on line voucher in order for them to print out your tickets. You would think your on line voucher would be your ticket to show each time you get on and off, but that is not the case. You have to have an actual physical ticket they print out for you.
