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.)

Yeah, this seems like a much more likely option. Get a ton of good, completely unique scans of real world environments you could never replicate in testing and even if your product sucks and you fail entirely, you’ve got a really good dataset to sell to a big company that’s close on a product and needs data to enhance/refine on.
