Several years ago I traveled from Rio De Janeiro to Capetown on a freighter (although not nearly as large as this Triple-E ship!) There are some ships that still offer paid passage and staying on board of one of these enormous ships, manned by just a small crew, is an amazing experience. I got to visit all the areas of the ship, could wander about during the day, hung out on the bridge with the night watch, visited the engine room etc. Being on the bridge when the building sized ship docks at port is incredible to watch.
