Washington Park - free parking

[lslmustang 15]

Has anyone done the new Free parking at Washington Park and take the streetcar down to the game?  Just curious if the first 100 cars are there early, if there is a huge wait after the game? Any challenges? I'm thinking of doing this for the Cleveland game and just want to have an idea what to expect and what time I need to be there to get the free parking.

Thanks for any input
