Although really looking forward to this tour I was a little concerned with the 15hr duration. I didn't need to be as the day went quite quickly and very smoothly. The bus trip was fine and we had a nice little stop for food around half way. Our guide was a lovely lady who was very entertaining. We had the perfect weather although in Winter and Washington did not disappoint. Arlington cemetery was very moving and it was great to see the White House etc. We went to the Indian museum which was OK but the food was terrible so try and avoid eating here. The space museum was very interesting and worth a visit. Entry was free which was very nice. If you intend to stay in New York this tour is a must as you have Times Square etc. then the luxury of seeing the capital.
Everything we went to was good however there was Spanish and English on our group so our tour guide would say the English info on the bus before we got the the attraction and then the Spanish when we were there, so me and my partner would be piecing the info together once infront on the attraction!
A very good and worthwhile trip made especially valuable by the guide. She a real pity we have forgotten her name was informative about historical background and the sites, very pleasant, humorous, made the tour feel special, and was good at keeping the tour to schedule. This was a good achievement because the tour includes a lot in the long but interesting day. Our driver also made great efforts to help us see as much as possible. There was enough time to eat, and a range of museum and street eating options, at the main Washington stop. However its inevitably not possible to fit in too much during this stop, from the huge amount there is to see, so thinking ahead about priorities including how much time to spend eating is probably a good idea.
