Also, cleaning kitchens is a huge part of the job. Hotel rooms either have no kitchen or a very minimal one. You're not going to learn how to clean an oven or load a dishwasher in a hotel room. (And loading a dishwasher requires categorizing thousands of things as dishwasher safe or not! Stainless steel skillet, yes; cast iron skillet, no; etc.)
