Is there free parking anywhere near there? If not, do I need a credit card to park at a meter since it's a plastic world nowadays?

No free parking. Meters and yes youh need a card they do not take coins. There are alsso parking lots across the street

Youll need cash or credit. But if you have online that will be best option or there are other less stress like golden valley. Brooklyn park that offers the same services. Goodluck.
