I arrived at the Cuttyhunk harbor with a reservation and was told they could not find it. after they continued looking and no reservation was found they offered no resolution. It was at that point it was only after I insisted and I indicated I had a written reservation/confirmation in hand that they allowed me to go to the assigned dock which was not occupied. It was unsettling to arrive with a reservation for accommodations on land to be told that no reservation existed. I would like follow up on this incident.
