As CPRich mentioned, be aware that technically per Marriott's rules, you should have only received one stay credit per night. So while you did receive multiple stay credits (and I have seen posts from others stating they also received multiple stay credits), someone might not get multiple stay credits per night or if it was found during an audit, they could lose those extra stay credits.

So personally, I wouldn't completely rely on it working out and plan accordingly, but as always, YMMV.
