It’s clearly shown on your offers — both the print mailer and online. Circa Hospitality Group publishes the dates of validity for gaming offers on the offers themselves. The burden is on the customer to read the offer and understand the terms and conditions. Any complaint about Circa Hospitality Group not revealing the terms or “hiding stuff” shall be considered invalid.
You might not like the terms and conditions, and you might feel that you should not need to know or read the terms and conditions, but there’s no funny business or bait-and-switch here. Nothing was “voided” or last-minute changed because the terms and conditions were always clearly stated and available for review. That part is indisputable.
Among the downtown properties, the only gaming properties that appear to not have blocked dates for at least some form of offers during the NYE period (exact dates vary by property/group, but generally include most of December 27 – January 2) are Golden Nugget (room comps are not available, but free play appears to be available) and the Plaza (all offer components appear to be available). I’m leaving the Downtown Grand out of this because the gaming offers (and casino marketing, and casino hosts) there are so wildly inconsistent to the point of being effectively nonexistent.
I’ve said it before, but usually in the context of Strip properties. If you try to impose the operating norms of one property/company onto another company/property as your set of expectations for how “things should be done,” you will only end up being disappointed.
