Overnight parking allowed right near the park and river. It costs $6.35 and you have to renew at 6AM at the kiosk or easier to do from bed on the app. Park near the river not River Street to avoid noise. Great little spot. Seems you can also park on the Coolidge Park lot a couple minutes away. Lots of good restaurants nearby and a great vegan spot called Cashew. Jackfruit nachos are the best!
