Our guide Carlos was a wonderful host, fully prepared with accurate cultural information and a precise itinerary. Our bus driver Roberto was very professional and careful behind the wheel.

Our tour guide, Quentin, was incredibly enthusiastic and worked so hard! 🙏 He arrived at the designated location well in advance to pick us up, but worried we might not be awake or well-rested, so he didn't contact us beforehand, only calling at the agreed time to let us know he had arrived. Today's trip was a full 10 hours, and he really set off very early, not driving us back to New York until dark. It was an exceptionally tiring day. He introduced every point we passed along the way. In Washington, some attractions weren't included in the tour itinerary, but since we happened to pass by them on our way to the next attraction, the guide still provided explanations and information. Overall, I was extremely satisfied with the trip. I originally wanted to rent a car and drive ourselves, but for various reasons, I gave up. Group tours are convenient and effortless; I don't have to think about anything. I would definitely join a group tour again if I have the opportunity. Thank you again to our tour guide; you worked so hard!
