I'm sure Marriott won. But I also feel like I won. I went from a long-time Marriott Gold, years away from achieving LT status at any level, to LT Gold and by end of 2018 or early 2019 LT Plat. I'm not thinking about earning status every year now, which brings a feeling of freedom.
I have many many more hotel choices at which to use my benefits in the future then I did pre-merger.
There were some losses, but overall I feel like I personally came out pretty far ahead.
