Marriott is launching a new program August 18th which will be the same for all of Marriott Rewards, Starwood Preferred Guest, and Ritz-Carlton Rewards.
Accessing frequent guest accounts, and even making reservations, is expected to be offline most of that day. In addition Marriott Rewards and Ritz-Carlton Rewards accounts may be unavailable during overnight hours between now and the 18th. These overnight outages shouldn’t affect Starwood accounts.
Starting August 18th though you won’t be able to use previous travel package redemptions for a month.
