The global hospitality industry will generate some $550 billion in 2016, according to Statista. Anyone hoping to join this booming industry will most likely do so via the traditional hospitality school system. And yet, not everyone considering a career in hospitality is ready to commit years to years of schooling. Front desk staff, even those in sales or I.T. are much more likely to test the waters to see if the industry is a great fit. Or maybe they need to brush up on current industry trends. MOOCs, Massive Open Online Courses, offer a much-needed respite from the stale and slow-to-adapt hospitality education system.
