I've also been in contact with Darryl from Seven Stars Insider, who seems to believe this is much ado about nothing. He claims that the benefit was never a "guaranteed 4 nights" in the past, according to the official rules:

"At a minimum, one room per night will be provided, with a maximum of four consecutive nights", is how it read in the rules from 2015-17.

That may not be a hard guarantee, but in my opinion, it's pretty damn close.

And this year, they knowingly left the complimentary room benefit out of the e-mail and website chart, when it was there in prior years.

For some reason, Darryl is not alarmed by the change in the benefits e-mail and the website chart.

I think Darryl is being too dismissive. They changed the wording and the chart for a reason -- and the most likely scenario is that they've eliminated or curtailed the free room benefit. While I agree this isn't certain, and you can't ever draw 100% conclusions from anything CET does, I'm much more worried about this than he is.
