I bought the 24 hour all loops tour and it was fantastic. I got to see all the famous sites I would always hear about. My only regret is not getting the City Sights DC FlexPass. Being that I went to Madame Tussauds and the Newseum I could have got that in the flex pass plus another 24 hours tour and the Dc nigh tour. Don’t make my mistake, get the flexpass.
