While this is a good way to see the monuments, I would not recommend this tour if you are hoping to learn anything about them. The tour guide did not give us any information once we were at the monuments, and some of the information given during the rides was incorrect we were told that George Washington became President in 1850. I have taken similar tours with other companies that were much more information rich and had much more interesting tour guides.
Definitely worth doing if you have a day in Washington. We saw many sites in a short time. The guides were knowledgeable and fun.
Our guide Sally was really knowledgeable and also our driver very nice and helpful. I was kind of worried the tour be cancelled due to the number enrolled, but they make it with only three of us. Thank you for the great day.
