We had good experience picking up with Hertz on Easter Sunday. They met us at the Ferry Dock even with ferry being about 30 minutes late. She was waiting there and we quickly did paperwork (they didn't do a formal reservation just took my name and number and told me that they would be there). We just left the car in the Moorings lot on Tuesday morning with the keys at the front desk. I called a couple of hours after to confirm they had picked up the keys and all was good.
