The Greek island of Santorini offers some of the most spectacular scenery in the Aegean. But residents argue that their island is suffering from “cruise overkill”.

Officials announced last week that unrestricted calls by the vessels — which on busy days dump more than 12,000 passengers onto the island — have caused uncomfortably cramped conditions that are damaging the overall tourist industry.
