Marriott apparently updated their policy without informing people. Now all Legacy Marriott properties are basically ok to have blackout dates..
i. Participating Properties from the following Brands may cap the number of standard rooms available for redemption on a limited number of days: The Ritz-Carlton®, EDITION®, JW Marriott®, Marriott Hotels®, Delta Hotels®, Autograph Collection® Hotels, Renaissance® Hotels, Gaylord Hotels®, Courtyard®, SpringHill Suites®, Protea Hotels®, Fairfield by Marriott®, AC Hotels®, Moxy® Hotels, Residence Inn®, TownePlace Suites®.
So...... Why would Marriott have already implemented a seasonal chart to get more points out of us and then limit us the ability to actually redeem them when the demand might be high..... I think a points devaluation might be in the work soon.
