When walking in the terminal you should see a line for the Haven. Maybe someone else can chime in about what side its on while looking west. From 2019.... it was on the right. Large sign for Haven check in, we showed a woman our Edocs and she directed us to a separate security line. We were then directed to the Haven checkin, a smallish room to the right. It was in there we got our cabin cards, about 11am we were escorted to the Haven
