Here's the problem with this entire thing. It takes a very outlier scenario, that while very real, does not happen in the overwhelming majority of stays anywhere/anytime/anyplace and it turns it into/implies some kind of doom and gloom, this goes on all the time, "The Sky Is Falling" thing where "OMG!" the entire hotel/industry/parent company has gone to hell in a handbasket when none of that is remotely accurate. It's all sensationalistic hyperbole.

I've been in the industry a very long time working for corporately managed Marriott properties to some less than desirable Hilton franchisees and everything in between. Here's what I can tell you as basic truths. John Q Public does not read (or even know that), sites like this exist. They also have no clue about rules/benefits/etc. for fill in the blank loyalty program of your choice.

Will a parent company eventually get involved if something major goes on for a long period of time? Of course, but that's they key...major and a long period of time. If this was a one-off that happened for a day or two, it doesn't matter and it won't move the needle at all. If they're doing this everyday into perpetuity, eventually, they will get called out on it but even then it will take a while? Why? Because as you know, the system is rigged that way. So few people fill out post stay surveys and write reviews and with each property more than likely only having a QA audit once a year, what goes on the other 364 days a year is well......

Like I said upthread, people think that the parent company is some all omnipotent being that knows all and sees all. That's total BS. They're not. They only know what one day a year of their own observations tell them plus what they see via official post stay surveys on the sites they track for reviews. All you can do in this scenario is fill out the survey and speak up and even then, don't expect change overnight.
