A good sign as to whether they know/understand/recognize your LTD is whether they ask you to run your card for incidentals at check in. If they know/understand/recognize it, they will never ask you for this, if not they will. What I find funny is when there are multiple properties in a country/city, and when one is familiar and does not ask and the other is not familiar and asks, and when this is pointed out gives some excuse like "legally we have to do this", and you question and ask, "so property x, y and z are all breaking the law", which follows with a blank look and the front desk manager being called.
