I did this tour as I wanted something that would give me a quick pitstop around the main sights in Washington, and the tour did what it promised. Pick-up opposite Grand Central station was painfree as the english-speaking tour bus was there when I arrived so there was no hanging around on the street (although those waiting on the German bus had to stand about). The trip was 4 hours there (departed at 7.12am), broken by a half hour stop halfway for food/comfort break. Then onto the Lincoln Memorial, the Korean and Vietnam War Memorials, the White House and the Capitol. In the middle was a trip to Madame Tussauds which I wasn't fussed on doing but it was ok and only lasted half an hour or so. Then a 5 hour return trip to NY as we hit traffic, again with a quick comfort break halfway. Tour guide was informative and engaged with everyone. The only negative was the very very squeaky bus - given 9 hours are spent on it some WD40 would have been useful! However all in all a good trip and I would use Viator again.
Good value. A long day but you certainly get to see everything. Washington is too big to really do all this in one day on your own. Friendly guides. Recommend.
Overall a good experience for a day trip. Tour guide was informative and helpful. We went to the iconic places for photo taking (e.g. White House, Madam Tussaud) and finally National Air and Space Museum for a tour and tea. Ride was 5 hours each leg, that leaves us around 4 hours exploring Washington so it was quite rush but overall a good experience for a day trip
