What’s the best way to park?

There's a parking lot next door so you can park.

In a lot .... There's street parking at one hour meters on spring st and Hudson st ($3.50/hr) but the street signs could be confusing for out-of-towners.

There is a parking lot right next door, you have to pay for.

Most likely a parking lot in the area. Parking lot is right next to the museum
