Cruise Quest

Hi we are docking in Santorini in June and wondered if anyone has caught the water taxi back to the port from Oia? We are thinking of going up the cable car to Fira, bus to Oia, walk down the hill to Amoundi bay with a view to catching the water taxi/ ferry back to the port early evening. I can only see information about the water taxi to Oia! I presume they come back but would love to know if it’s possible please!
