I have to say I was afraid the tour would be too rushed and crazy, I was with my elderly parents and all... It turns out to be a pleasant and relaxing trip! The guide, Marcos, was just amazing! Very fun, calm, professional and knowledgable. He made sure verybody was on schedule by being nice and not rude like guides could be. We really enjoyed the trip, the bus was clean, comfortable and modern (with USB to recharge phones) and our driver, Joseph, was great too, polite and professional.
We didn't get to see the White House because there was a meeting happening there, but that's not something we have control of. We enjoyed more time at the museums, which was good.
Overall a great experience for someone who doesn't have much time but wants to see the highlights in a very comfortable way! I recommend it! Bring snacks!
