I think it's cultural. As a child, I travelled with my parents to parts of the U.S. (New England, etc.), Canada, Japan, Korea, Thailand, Malaysia, Singapore (where the hotel was weird and insisted that I stay in a separate room as a 12-year-old - which my parents thought was a weird morals clause but I thought was just a grift to make more money), Indonesia, India, Israel, Greece, and Spain. Some of those hotel rooms were pretty rudimentary.
