Is there parking for this museum..or do we need to use a lot?

There is a parking lot across the street. We parked there for free when we went but it was the off season

There is a parking lot accross the street, during the summer they charge by the hour, off season you could(as of last season)park in this lot for free(circumventing the pay as you go street parking), as long as you can access the lot(gates open) it should be fine to park here.

There is metered parking on the street or you can use a lot.
