Early in my travels for work, we organized a corporate rate at a Hilton in southern California. We had stayed there a few times and determined it to be our future preferred hotel. We were always treated well there.

Immediately upon checking-in the first time after booking under our corporate rate, we (all HH Diamonds) were told no more free breakfasts and no more preferred rooms.

I emailed HHonors customer service and was told "The hotel is incorrect. You continue to get all benefits you previously received regardless of your corporate rate." HHonors compensated me more than necessary and at our next stay at the same hotel, all issues were resolved.
