Yep. When I travel for client work, book through Concur, the travel desk, etc., and pay with my card, there is no issue whatsoever. But traveling for training, conferences, etc. where the room is taken care of, nothing.

I sort of get where they're coming from, and it's always been the case (with Hilton) that "them's the rules", but it has always struck me as something that is disproportionately likely to tick off valuable customers - the folks in this situation are often road warriors attending corporate functions, and it would seem to me that the cost to deliver benefits would be less than the potential impact of the perceived slight of treating them like nobodys. But who knows.
