I think what Eugene was getting at was that certain of these double point promos have a particular rate attached to them, which often can be higher than a discounted or other package rate that can be found at the hotel.
If that was the case, then I do not think he will get the bonus. However, if any stay at almost any rate at the hotel would qualify, then the bonus should be posted in some way, shape, manner or form, be it posted in the normal way or "silent."
