Watch out for T&Cs: if you stay at the Fairfield by Marriott you could accumulate half the points and nights

You know the small print standards? the ones you are obliged to accept on pain of not receiving a service? here these terms and conditions are constantly changing, and often unanticipated news is hidden between the folds of the subparagraphs. This is more or less what happened recently with the update of Marriott Bonvoy's T&Cs, with the Downgrading of some Fairfield-branded facilities.
What changes
In this article:
Normally each stay in a Marriott chain hotel generates a qualifying night, i.e., useful for status renewal, every night spent at the hotel. And for every dollar spent 10 Bonvoy points to be used for free stays. Until yesterday, only facilities that fall under the longer stays category had a different accumulation. Now, however, things have changed and some Fairfield facilities will also change their accumulation rules.
Fortunately (in Europe) this change affects, at the moment, only Copenhagen's Fairfield Hotel, but the new rule applies to all facilities in the EMEA area, or Euopa, Africa and the Middle East. This means that all other hotels, including e.g. the beautiful hotel in Kuala Lumpur, will allow Bonvoy members to accumulate 10 points every dollar spent and 1 qualifying night every night stayed. The hotel in Denmark, now the only sign in Europe, will have values halved.
Every dollar spent will accrue, net of any promotions, only 5 Bonvoy points and, even worse, only one qualifying night for every 2 stays. Truly a downgrade that for me zeroes out the chances of staying at this hotel.
In conclusion
The hotels are not owned by the chains in 99% of cases, this means that they pay royalties to participate in the family, with this downgrade I believe that Fairfield Copenhagen management intends to save on franchise costs, but I think it will boomerang in terms of bookings from customers interested in points and status, while nothing will change for those who book through booking and other channels.
