An elderly woman told the author that living on a Princess cruise ship was cheaper than a nursing home. The author calculated that a cruise would cost $135 per day, compared to $200 per day for a nursing home, and provide many amenities. On a cruise ship, seniors get meals, activities, housekeeping, and an ever-changing view as the ship sails to new destinations around the world. The author plans to spend their retirement on cruise ships rather than in a nursing home.
