It's a pretty and historic park, the plaques are enough to give yourself a kind of self-guided tour. So there's really no need to spend any money once you get there. There probably will be people trying to sell pamphlets for a "donation" or their novel about their assassination theories. It is pretty crowded, even when I went on a Wednesday afternoon. But it is a very worthwhile stop if you're gonna be in the area.
