Are photography and social-media posts acceptable around island day trips and boat tours?

Island trips range from public ferries to speedboats and private charters. Confirm the operator, insurance, lifejackets, sea conditions, inclusions and final return arrangements. Photography rules vary. Ask before photographing people, performers, religious spaces, private property or security areas, and respect signs or staff instructions. Avoid publishing identifiable people in sensitive settings without permission. Sea-trip note: Ferry schedules, sea conditions, prices and last departures change. Confirm the return plan, operator, lifejackets, weather and inclusions on the day.
