Is there parking. Should we be early

The is a parking garage over by biscayne blvd

There is parking. Street parking and parking lot parking. Not sure about a garage. Getting there early is not going to change to much. They have set times when the boat departs. It's about numbers.

Street parking or locate a nearby parking lot

There is parking. And it does not matter is you're there early. Enjoy

There's is city parking you pay the meter for how long you will stay and they give you a receipt to put on the dashboard of your car to show you pay for parking
