Good points. When going on a cruise the ship and the airplanes are the safest parts. People don't think twice about jumping in whatever taxi or bus that pulls up at the airport to take you to the ship, but that ride is easily the most dangerous part of your trip, other than your drive to the airport from home which is probably more dangerous since most of us are not holding a CDL which requires a certain level of training and at least a medical clearance for the driver.
What about that tour bus in Guatemala? Or the jet ski in St. Maarten? People need to understand and manage risk.
