Bus ride could have been more comfortable. Tour guide left us at some of the attractions to see without any explanations. We tried to listen in to other guides telling their groups about the place like Lincoln Memorial or White House or Space museum.
The Tour was reasonable and the guide was very good. However, there was a lot of time wasted. I believe the Tour should have included Arlington cemetery rather than the Wax Museum!!!! and the time at the Smithsonian (aeronautics) was also too long...
I found the Washington tour very interesting, and we certainly saw all the main attractions/land marks. However, I was very disappointed with the main tour guide. While his knowledge of Washington was extensive and he did have interesting information for us, he often provided too much detail - especially with how the US Government works (eg, House vs Senate, how the electoral college works etc), which I didn't think was necessary. The Spanish-speaking tour guide would often jump in on his 'lectures' to provide more interesting facts - such as what landmarks we were passing, and providing off-the-cuff tourist tips for New York. Also, on the way home they showed a movie on the small TV screens which had no sound... I don't quite understand why they bothered!
