If you are short on time but really keen on seeing DC, this is the best way to do it in my opinion. Marcos, our tour guide, as well as Alvaro, our driver, made a great team in showing us the highlights of Washington. Considering you end up crossing 2 states to get there, the tour does a great job at condensing so many sights in such a short space of time! The pick up is early in the morning at 0630, but then you have the opportunity to nap on a very comfortable coach. They make regular stops for bathroom breaks and you have plenty of opportunities to stock up on snacks should you wish to do so. Marcos was like a fountain of knowledge, he shared all the interesting facts about everything we saw throughout the tour and the fact that he did so in English and Spanish was all the while even more impressive!
All in all, I definitely recommend this tour to anyone who wants a taster of what Washington has to offer.
