I'm guessing that since both SPG and Marriott have been making a distinction on the welcome amenity points and at least SPG on MAGC, we'll see the combined program give twice as many points at more expensive hotels, we'll see perhaps 1,000 at 4Pts, aloft, element (plus RI, TPS, etc. on the Matrriott side) and 2,000 at what are considered full service properties.

AFAIK element hasn't been doing this, but Marriott extended stay properties normally don't do housekeeping every day on longer stays anyway, so I don't think they'll start offering points for a MAGC program.
