If you are doing the sightseeing in Washington you pick which attractions to go to . We chose 4 attractions and enjoyed them all. You ride Big Bus in washington with the pass and they are located at Union Station. The Smithsonian's are free and just wonderful. I also recommend getting a train pass to get around Washington. We did and it worked well. For Trains and Buses. Goodluckhope this helps . P.s. I highly recommend the night tour excellent.
It's free, like a public park.
It depends on which boat/tour you take, between 65$ and 31$. Getting a sightseeing pass or city pass for multiple events/places
Night party cruise is about $30-40
