The net outcome of the change, as documented elsewhere, is that some properties get cheaper, some get more expensive, but on average, across all of SPG and Marriott, redemption are slightly cheaper.

Every individual stay pattern will yield different results (though I don't accept the "the properties I stay at went up, so the entire program was obviously devalued"), but on aggregate - neutral to slightly positive.

With the many other problems the integration has, this one isn't worth re-hashing, again, IMHO.
