Are companies required to inform you when the hotels are being raised in price with cash rates? So what makes you think they need to do this with points? Do you think that point prices should never go up in price? Is it because you talked about it with a few dozen people on the internet?
News flash. High-demand hotels, in a strong economy, have gone up in price. Sure it sucks, and thanks for letting us know. No need for all of the outrage and claims of bait and switch.
