There is a particular RI at which I've been staying about 7-9 times a year, with the first stay about six months after it opened.

Overall, quality on most aspects has been consistent (ie, things work, rooms are clean, landscaping is excellent, FD folks are friendly and efficient, etc.) though the breakfast has steadily deteriorated.

Two months ago the gravy was particularly awful, I just passed it up, but another guest thought it was bad enough to bring a sample to the front desk for a show-and-tell.

The following morning, breakfast was much improved. However, it seemed to have been fleeting, since it was back to being less than optimal during my following stay, about a month later.

OP, to sum this up: even though every other aspect of the stay is fine, I do give demerits on the surveys (and indicate why), perhaps there's a particular area that's causing the results you're seeing.
