I had a chance this morning to search my notes regarding transportation from hotel in Ravenna to the port. This is the information someone in our cruise specific group posted. The information was from their hotel. This is from August 2022 so could have changed. We used #3 and, in October, 2022, he charged 10Euro per person. He arrived a bit early for the pickup and got us to the port very quickly. I would use him again. His phone number works via WhatsApp.
