We were running late into town due to earlier construction on the roads and we called the tour company hoping they'd let us change the date of the tour. Steve working the phones at HQ let us know they'd hold the tour cart for us for a reasonable time while we made our way down town. Tim the driver was cheery and enthusiastic when we pulled up and helped get our three kids into the cart fast. Off we went for a brief but fun nighttime tour of DCs biggest monuments. We got about 15-30 minutes at the FDR / MLK memorial site, and 45 minutes at the Lincoln / Vietnam / Korean memorials for walk around time. It's not a tour for long walks around every key site in DC, but it's a fun overview of the mall area and you get to see the Capitol, Jefferson, Washington, White House, National Mall, Cherry Blossoms, Lincoln, FDR, MLK, WW2, Vietnam, Korean sites. The vehicle is great being open air but with seat belts and we felt safe with the three kids (9, 6, and 3) the whole time. The ride is part of the attraction so keep that in mind. I think the nighttime price is a little high for what you get (the daytime tour price seems more in line with what you get), but no complaints.
