Yes I have experienced it very much in Germany - yes I have gotten an accessible room as an 'upgrade' at CY Berlin for a EUR 60 rate. However they can't punish you for giving you a room that is of a lower category (cost less) than the one you booked, no matter how low your LNF rate is.
Of course it happens that when OP arrives so late and in the US things are usually overbooked, and OP ought to get some kind of compensation since he hasn't indicated in any way that he wasn't coming.
