A VERY long day! But if you're on a tight schedule and want to pack in as much as possible, then this is a great option - you couldn't see this much of DC on your own in a day. Our guide provided tons of great information and we saw all the major monuments in DC. Apart from the cheap and nasty lunch and dinner options available to us, it was a good day.
The trip to Washington was great! A must do when on a tight schedule, the bus was comfortable and good stops along the way for restroom use and food pick up! Saw many great things the only disappointment was our tour leader who didn't have much of a history background of things and told us a few times to google a question. He also told us he has only been in America for 13 years (and definately was not a fan of Obama and American politics) which did dampen his attitude of what we saw, which was a real pity! He wasn't a happy man, which made the trip not as great as it could have been!!
Sue: Very long day but really enjoyed it. Bus trip was a little bit too long but guess you cant help that.
