We stayed there in May 2018 for one night. The night we stayed, the parking was free. We were gone on a cruise for a week, left the car and were charged $8.00/day. However, this time they charged a shuttle fee to the port of $16 pp rt.
Shuttle either goes to the station or the airport no other destination is offered you would need to call the hotel and ask if that were possible
A cab would be the other option & they are cheap and plentiful
