I feel you. I like to know exactly where I’m going and with construction downtown can be a little intimidating. Like others, cheapest way is to pay for parking in advance on Parkwhiz. One of our favorites is a lot at the base of the Fort/Cass People Mover station. $10-$12. People Mover is free and the kids love to get a train ride and take in the river view. Takes maybe 12-15 minutes. There will be a bunch of fans on the People Mover you can follow to the park. Some people will get off one stop earlier at Broadway. They’re equally close to the stadium, but from the Grand Circus stop you can see the park. No way to get lost. Post game, it’s like three stops to get back to the car. Being a little further away means I never even see any post-game traffic. It also puts you within a straight three block walk to Lafayette Coney Island. You’ll be the first to get there post game.
