It's been a few years since I worked at St. Regis (it was pre-merger) but I was the hotel SPG Champion. I saw all the paperwork and got to do the SPG reports to send back. This St. Regis was one of those resorts where tons of SPGers used their points for a week's stay over Winter and the Winter holidays. There were times that we were over 50% SPGers on points. If we were under 95% occupancy (I think that was the threshold), the hotel was given $100-something per night per room. If we were over 95% occupancy, we got a tiny bonus. With all those redemption during our busiest time of year, we lost money, since we were charging non-points rooms at $1500+ prime weeks. The monthly business meetings with the owner were not pleasant.
