I'll chime in with the recommendation of Plugshare as well, although sometimes when you call an audible and stop at an unexpected charging station without time to research it, it can get a bit tense! And if you find that Plugshare doesn't have adequate instructions (which would be rare), make sure you help out your fellow travelers and add your own comments to help others.
I would not say that finding the charging stations is always intuitive though. There are two stations in particular that I've found very challenging. One is in Rockville, MD where there are two garages that for all intents and purposes look the same, so you have to first locate the right one. Fortunately the right one has a sign on it that notes that Tesla Superchargers are within, but unless you pass by that garage first, you won't know that! The other one, which hopefully by now is fixed, is the mall in Syracuse, NY. At the time the nav took us around the mall in the wrong direction, and by the time we got sick of looking around and checking Plugshare, we had turned around and gone around the other direction. Sometimes it's not intuition, but just a 50/50 coin flip.
