Santorini struggles with over-tourism, leading to proposals to cap cruise ship passengers at 8,000 a day. Locals and businesses feel the impact of overcrowding on the Greek island's infrastructure and economy.
Cruise ships have hidden features like morgues, jails (called the brig), superstitions about Deck 13, and designated areas for crew members to unwind. Some ships even offer Alcoholics Anonymous meetings for guests in recovery.
