Rick Macpherson over at the unusually named Malaria, Bedbugs, Sea Lice, and Sunsets has an excellent post on why you should think twice about stepping aboard for fun and sun on a cruise ship. He details the new uber cruise ships, the Genesis Class and thier/your potential to kill off the places you love. In case you are not in the know, Royal Caribbean has announced it will build cruising’s biggest ship ever with the development of a 220,000-ton, 5,400-passenger ship (43% bigger the Freedom Class, e.g. Freedom of the Seas , that debutset last June). The price tag ~1.5 billion dollars and they have two ordered for 2009. Spend some time reading over Rick’s very informative and interesting blog.
