Why would they Google it if it didn't occur to them that it would possibly be a requirement? They might if they were unsure, but in this case, they were sure (and just happened to be mistaken). Consider the case in the other thread about passports to Hawaii. Do most US citizens Google passport requirements to Hawaii before planning a multi-week vacation there? No, they don't, because they know it's not required - why would it even occur to them to double-check? The couple in the OP were in the same situation (except obviously that they were wrong).
