Today, travel may or may not be much easier depending upon the destination you choose (e.g. Mt. Everest, the Amazon rainforest), how you plan to get there (tour bus, cruise ship, or oxcart), and whether you decide to “rough it” (see extreme tourism and adventure travel). “There’s a big difference between simply being a tourist and being a true world traveler”, notes travel writer Michael Kasum. This is, however, a contested distinction as academic work on the cultures and sociology of travel has noted.
