I just checked this morning and Hilton still offers 7,000 points for $100. Since Hilton is my only hotel choice, I assume that Hilton is the company that invited me to E-rewards. Maybe that makes a difference.

Or maybe E-rewards is doing A/B testing, testing different mixes of redemption offers. Or maybe they are (as a previous poster theorized) changing the Hilton offer in tranches. But why would E-rewards need to make the change one batch at a time instead of all at once, IF E-rewards had already decided that 7,000 points for $100 was too generous? If they are doing A/B testing then I am in the lucky group that has not (so far) been changed. And, if they are testing, and the change shows that the change is not achieving the metrics that E-rewards thought it would meet, then maybe it will be rolled back globally. (Until E-rewards thinks of another A/B test to run ...)

Just my 2cents. I obviously have no real knowledge about what E-rewards is doing. But I work at an E-commerce company, and we are doing A/B testing of one kind or another almost constantly. So that is why my thoughts went that direction.
